RE: Honda 2000 quiet box, I'm back!!
If you are truly concerned that you might catch the cardboard on fire, you can make homemade fire-retardant and spray your flammable materials, let them dry and then move forward.
Here is a quick link to some mixes you might consider:

RE: Honda 2000 quiet box, I'm back!!
The 1st box I built did not catch on fire but did fall off the back of the trailer while driving down the road... Grin. Luckily it was wired on, so it was destroyed but did not fall into traffic.

RE: Back up camera recommendations?
Gone through a couple wired to running lights like Flyboy. Some have worked some needed to be returned. Current one has good range through TT and has lasted two years so far.

oh thats not cheep haha..
The cheap ones would not make it from the back of the 30-foot TT to the front of the truck. And one of the cheap ones I tried kept failing due to water intrusion into the camera.

RE: Harvest Hosts
I joined to see what was really on the list, to find the local Wineries that allow overnight, and have not used it yet. I did look in my local area, and there were some commercial places and some places owned by people who just like to host other RV'ers. Here are the current statistics:
Wineries 771
Farms 1546
Attractions 1194
Breweries & Distilleries 545
Golf Courses 0
Boondockers Welcome 3295
Total 7352 / 7789

RE: Towing with lifted truck; need assistance
For all the reasons posted, you have reduced your towing capacity and stability. I would call the folks at Propride and see what they suggest you can tow with one of their hitches. Their hitch will give you back the stability you have lost with your modifications at the cost of $ and some inconvenience when hitching.
Not sure how any hitch could return any stability. You might sell the idea that it does not allow the trailer to further reduce stability but even that idea would have to go cheap.
Quite right. The Propride or Arrow will not return stability to an already degraded towing platform, but since they reduce the issues introduced by the trailer, they require less stability from the towing platform and get you back to about the same place.

RE: uBlock Origin ad blocker
There are multiple sites that look for Adblock, uBlock Origin, and likely others and then block their content from you if you are running them. Lately, some sites have gotten even sneakier and put some of the content required for the page to operate on some of the sites where they keep their advertisements. Neither of the tools blocks content that is displayed in a reasonable manner.
The net is this. If a site is unusable unless I turn off my ad blocker, I don't use it. There are too many alternatives that do not abuse the subscriber.

RE: Honda 2000 quiet box, I'm back!!
Call these guys. https://soundown.com/
They can specify a product they sell that will be thinner and provide similar sound absorption to the rockwool based on material testing (nice folks to talk to). They are also located in FL so in most cases, you will get one-day shipping for free.
Foam board is mostly worthless for sound absorption as it has insufficient mass. Drywall needs to be isolated from itself and other materials to get its full benefits using something like viscoelastic glue. Drywall also has a tendency to fail when it gets wet so unless you can keep it 100% dry it is a non-starter.
Sheets of metal have a tendency to resonate with the vibrations of a generator so make sure to use some product to dampen the resonation (you can put your foam/wool against it). On the plus side, metal has great mass versus its thickness and mass is what absorbs sound.
If you want to copy a working model so you know what you end up with will provide real benefit use the generator enclosures built for boats as your model. Specifically copy the ones built for Kohler 5e marine generators (sound shield). The Kohler units are gas motors running at 3600 rpm and are noisy as all get out. With the sound shield, you can actually seep in your boat. Their basic design is a metal box lined with sound-deadening foam (not the garbage you can get from homedepot or lowes).
You will still have the vibration transmission issue, but as you pointed out you are starting with a quiet model and it sounds like just trying to get a few more DB off the top.

RE: Honda 2000 quiet box, I'm back!!
Two more studies:
Wood box with a partial baffle and used ~1in think fiber glass insulation ~7db reduction
https://www.ajol.info/index.php/jasem/article/download/135141/124634
FRP panels with `2in Rockwool and no baffle ~18db
https://www.academia.edu/download/67787833/31568.pdf
What no one seems to have done yet is study a panel box built like this:
FRP | Mass loaded vinyl | Rockwool | Metal screen (think bird screen)
And then you would also need a baffle with at least two chambers.
I built a wooden box with a two-chamber baffle for the air intake and one for the output but used a significantly lesser sound absorption product than the Rockwool and got a 5db reduction in noise.
My next project will be built using the panel design above and the baffles. Of course, I need time to do it. :)

RE: Honda 2000 quiet box, I'm back!!
Great link. I followed the video to their page where they sell the Eco Route Silent Box. For the Yamaha ef2800ise the products costs $1,721.71. Looks like a metal shell with some sound deadening built in. The magic being the sound baffle box they designed for the exhaust end of the generator. If they used mlv on the shell, they could likely knock a few extra DB out of the overall box.
This guy described how a sound baffle works for exhaust nose the best I have seen and shows how he built his box. He also sells some very nice plans for wood generator enclosures and claims up to 5X sound reduction. https://www.youtube.com/watch?v=_qPRIq-9U-4
There is a 2003 study from India titled “Studies On Control Of Noise From Portable Power Generator” by Parvathi and Gopalakrishnan that looks at some unique ways to start deadening sound (should be some better studies since then but I have not yet followed up). I used their bed of sand trick on a whole house generator I had, and it worked as advertised. But the video I posted above appears to be the best homemade project yet.
I did drop the DB in my boat from 63db to 48db by decoupling the generator from the flooring using spring mounts I designed and had built. Since you appear to be wanting to use an inverter generator if you are going to mount it to your RV I would suggest floating the whole box in springs like the ones used in the HVAC industry to quiet hvac equipment. For my project, I used the springs out of a Mason CA-310
Mason CA-310 Spring kit
But you could likely just use valve springs.
Good luck and I would really like to see what you do and learn from your successes and failures.

RE: Data Caps Starlink
My kids managed to use >100GB in one day, this week, the last week we've used 378GB risk and that wasn't a particularly big week, during the pandemic I think our highest month was 3.5TB. We're fortunate enough to have uncapped cable, but I'm sure once it's just the wife and I on the road the Starlink speeds will be fine, just need enough to stream one show or do one video conference.
That is truly an amazing amount of data! I used to build large chunks of the Internet and huge data centers and you are passing more data than some of the data centers used... Your home usage is definitely not the use case for Starlink! Any chance you have looked at your traffic flows to make sure that is all you and not someone who has hacked some of your machines?

RE: Data Caps Starlink
Got the notification and went and looked at my traffic statistics on my home router (FIOS). With two adults working from home, two kids watching loads of videos/gaming, and I host some gaming servers like Minecraft, we burned around 100GB last week. It sounds like someone would need to be a huge data hog to reach the point they get de-prioritized. From a quality of service standpoint, it essentially moves the user temporarily from permanent to RV service. I have run two Starlink antennas side by side, one permanent and one RV, my experience was that both were very useable (not as good as fiber but better than cellular data). On average, the RV unit tested out at about 1/2 the download bandwidth and about 2/3 the upload bandwidth of a permanent Starlink installation.

RE: Pulled to the left when being passed by Big Rigs
How and why on Earth did this thread from last August come back alive?
Just went and looked at the dates, and it appears I did it. The answer is simple. The thread popped up under the newest threads page for me. It also appears as if a lot of people like the topic, so I am glad I dug it up (albeit mistakenly) from the dead. :)

RE: leaf spring broken..trailer legs?
They appear to provide 3 benefits...
1. They reduce the width between the things in contact with the ground, thus creating a less stable trailer.
2. They raise your trailer up on plastic supports that, when they deteriorate and break, the fall will likely damage your trailer.
3. They separate you from money that could be used for something you need or at least beer.
OK. So really only one benefit for the manufacturer, your money. :)

RE: Pulled to the left when being passed by Big Rigs
1L243 you have a very capable tow vehicle, so likely your question really revolves around comfort. I have a newer RAM 1500 with the coil rear springs, and its backside is a bit more squishy than I like. So I did most of the intelligent things mentioned in this thread, including working my way through three different anti-sway weight distribution hitches. I ended up with a Propride hitch, and it reduced the overall sideways movement to something I was comfortable with.
