My wife and I recently purchased a pre owned 2013 Winnebago Vista 26he with 29000 miles in near mint condition that had been immaculately taken care of by two ladies in their 60's. They were very particular and diligent in making sure all maintenance was regularly done. We drove it from Lincoln Ne to Albuquerque NM to the Balloon Festival on our first trip with it towing our new 2017 Jeep Cherokee. I installed a Safe-T-Plus steering control stabilizer before we left. All I can say is this is the most horrible handling vehicle I have ever driven in the wind. It was a white knuckle drive anytime the wind was coming from the side and especially on rough roads. The tires are good and they had the chassis serviced two days before we bought it. I thought possibly the alignment was off. I took it to a reputable shop in Albuquerque to be checked. He said that often they do a poor job of camber alignment at the factory. My records showed it had been aligned at 17000 miles and shims added to correct the caster. After checking it, he said the alignment was spot on.
All I can say is. I am selling this thing because it was like driving a billboard in the wind and I am not taking it on another trip. I can't imagine that any further work on the chassis would help this short and tall RV enough to matter, and I would bet it is the nature of this type of RV. It is not quite as bad without the Toad behind it but to put it mildly. It scared the hell our of both of us. I did not notice that the Safe-t-Plus Steering control was of much benefit either.. Has anyone had any experience with these short tall RVs of any Mfg. I did not see the trailers or 5th wheels being blown around as we were. Thanks All.

I am looking at the Thor Miramar 37.1. We like the floor plan and storage. My questions are about the overall quality especially the indoor cabinets and appliances. We currently have a Winnebago Sightseer and are used to a good ride and good quality of the Winnebago. We are looking because we need to sleep up to 10 people comfortably. Also we need the refrigerator to keep cold for a day or two while remote camping. Will the inverter on the Miramar do this? Thanks, any insight will help.

geerhed, Any slab sided RV will be effected by wind, from nature or passing vehicles - more so if trucks. The "rule of thumb" when I first investigated control 20 years ago was that any MH with a wheelbase to length ratio less than 55% would have handling issues.
Couple of years ago, in a three coach downsizing process we bought an Itasca 30T, as wife fell in love with the floor plan. Like yours, my ratio was near 50%, and it required maximum attention to keep between the white lines. I added upgraded billstien shocks, and Safe-T-Plus steering. Minimum improvement. Next was to install a heavy duty rear sway bar. Much better. Still a bear in extreme conditions, but not white knuckle in regular driving. Still requires full attention but as "super seniors" our travel days are shorter and stays longer -- and the wife loves the floor plan.
You may have a greater challenge than I as I suspect your chassis is 16,000 pound rating. Mine is 18,000, and a bit stiffer suspension.
Sadly, marketing drives the decisions and everything is least expensive component possible until you get to the premium priced coaches. Was that way when we bought our "retirement" coach 18 years ago, and hasn't changed. Given that handling is not even a consideration it's amazing that the accident rate is as low as it is.

We are giving it up on this Accident waiting to happen, Its up for sale. Drove 2000 miserable miles with the Safe-T-Plus steering control, and in the wind I really did not feel like it was much benefit, still fighting the wheel constantly. I don't need that kind of stress when on vacation. It drives decent under normal conditions but you don't always have that luxury to drive in perfect conditions. After we arrived back home I did the CHF (cheap handling fix) on the sway bars then took it out and drove on a windy day and still fought the side winds without the Jeep being towed behind it. It Aint worth it.

Do the low or no cost checks first.
Is the tire inflation set to the weight of the coach? Pressure shouldn't be higher than what is listed on DOT sticker. I ran my pressures up once playing around and at 10 or so PSI over I couldn't hold lane position.
Also as part of the weight check you want to balance as much as possible front/rear weights. Limited front axle weight may reduce steering authority.
Have the alignment check, in particular the tow set up. Have the tech set the tow as far IN as possible but stay within the Ford specs. If the front end is on the edge of tow out the steering can get twitchy and want a high degree of attention.
The cheap handling fix (CHF) will help, cost nothing but time.
A Safe-T-Plus or such may help but the problem is the rear end and as such you'll be chasing a symptom not the problem.
A rear track bar at the end of the cost range will tame tail pust from passing trucks and weather.
My coach is 32' built on a 18K lbs GVWR, 190" wheelbase chassis. 1/3 of the house is behind the rear axle along with all my liquid loading and my largest storage area. Wind push was a factor to the extent that I had to input as much as 45 deg of steering offset once to maintain a straight line in heavy sustained winds. CHP helped but the addition of a rear trac bar pretty much tamed the coach. Wind push is still there but hardly noticeable. The dynamics are too much to eliminate completely but a trac bar really make any movement very manageable.

My class A gasser is 34' 3" long and is on a 24,000 pound chassis and has the longest wheelbase available at its size, 228" (20" longer than some) and other than the factory option Sumo springs has no suspension or chassis modifications. Fully loaded for the road and full time living there is still a 1500 pound payload cushion, about equally split between front and rear axles.
It goes down the road very nicely, leading me to the conclusion many gassers need a stouter chassis and a longer wheelbase.

Dale Traveling : Somehow my reply to the post did not make it here thanks to IE.I got the old "Page Cannot be displayed" and the reply was gone.
I have done everything you had mentioned other than adding the rear track bar. The tires were at about 87lbs each, I am sure the tires could be at a lower pressure depending on the load. I did the CHF and tire pressure prior to the last test drive in the wind,(no liquid's or load in the storage and it was some help but not enough to justify going through all that stress fighting the road in the wind. I cant justify the expense of spending more money on this to "maybe" help a little bit because a little bit is not enough. Halloween is over so I am not in need of a scary ride. lol. We are going to look at the possibility of a smaller more low profile 5th wheel. The one thing I really don't like about the class A's is all of the noise, shaking and rattling. We had a 34ft Sportscoach and it wasn't quite as bad in the wind but we did not want something of that length again. I think the coach mfg's have all done a huge disservice to customers by building rigs that handle poorly and are noisy going down the road. They really don't care as long as they go out to the customer, Then its the customers problem to get them to handle better. If anyone wants an interesting Read called the "RV Industry Death Spiral" by Greg Gerber, Editor of the RV Daily Report. Its long but details many actual accounts of the horrors of buying New RVs.

" I have done everything except adding the trac bar" The trac bar and or sway bar is what helps the problem you are speaking to. I had a terrible problem with mine ine the wind. I opted to put a Helwig rear anti sway. This really cured the problem I suppose a Trac bar would also tame it down. My problem was sway on quartering winds so I put the sway bar on. I also added the safety steer and the CHF. I am quite pleased now with the performance. My coach has a heavier Chasis and a longer 228" wheel base. If you have had you have had it I hope you don't lose your shirt on getting rid of it.

After about 5 motorhomes, I have some comments about wheelbase and handling. My previous coach was a Vista 30W (earlier version of 30T). It was somewhat squirrely. Did the CHF, helped some. Played with CHF and air pressure. I then became interested in the 30T to pick up on some of the new features. Along the way I found a Sightseer 33c. More room, 22.5 tires and a better wheelbase to OAL ratio. It drives amazing and I had a real test on the I-40 between Amarillo and Flagstaff. In checking the chassis, it appears stock. My conclusion: weight, wheelbase, and the heavier chassis make a difference. And I found a 2016 model priced under any 2017 Vista 30T's that I had researched.

Wheel base to OAL is absolutely the key to handling. My old 35 foot Rexhall had a factory stretch of the standard 228 inch wheelbase to 242. With a front track bar and Safe-T-Steer I could drive hands off for 200 yards or more. Sadly, flashy paint jobs and interior fluff are more important to the marketing staff than handling. Interior utility is equally unimportant.
The fact that the previous President of Winnebago never owned, or even used, one of his products during his tenure is "nuff said".
