RV A/Cs do not cool like home. I don't know anything about your TT, but if you have a slide or slides and are going to be away for awhile, putting them in will help. Also keeping your curtains closed. I like to look out but when it get this hot, I only have the shade side ones open.
Get a running start in the morning before it gets to hot.

Best MH fan we have found. Honeywell Pro Series. Very stable underway.

Thanks for all your much appreciated responses. I've ordered a Kill-A-Watt and will forget about the service. The AC filter is clean but I need to check the coils. We bought a fan to circulate the air while we were camped. This forum definitely rocks!

How big is your TT? How many BTU's is your AC?
I have a 31 foot Winnebago. It has 2 AC's. I used to be able to run only 1 AC (13.5K BTU's) on shore power at full blast and it could not keep up at 95 degrees. In partial shade, temps would rise to the low-mid 80's in the heat of the day. In full sun, it would get up to mid-upper 80's even with all my shades on the windows. It just couldn't keep up. We ended up closing off the bedroom area to keep it in the mid-80's.
I've since upgraded/replaced the front AC with a 15K unit. That helped a bit (being newer and bigger). I also set up the rear AC where it could run as well on a separate connection. Once I did that, I was able to run both AC's on low and stay very comfortable even at 95 degrees and full sun.
So, if you have a 25 foot TT and only 1 13.5K BTU, then its likely that your AC just doesn't have enough cooling power to sufficiently cool your TT.

We have a 24ft TT and one unit. Not sure of the BTU rating but would imagine it's at the lower end. I'd have to check. Looks like I need to keep my vacation time in it to days below 90 degrees. Running the water heater off the gas may also help some. Thanks again, everyone.

I am of the same opinion/experience!
Don't expect the RV A/C to be like a home A/C - a 20 degree drop is about the most I have ever experienced. And, when it is is really hot, don't run the a/c fan on low - I have found that leads to compressor freeze-ups.

In our 33 foot 5th wheel when it is 90 and above we generally shut the upstairs off and we stay cool. Once the sun fades were good.

I guess I don't understand the comments above about using fans to help circulate the A/C's cooled air?
Our roof A/C is ducted throughout the RV and hence the cooled air is circulated throughout the interior as the A/C operates.

If your compressor's runnning it's probably not a voltage problem.
You have very little insulation and big (compared to wall area) single-pane windows. In a hot climate, especially if you have sun shining on you, you're toast.
You might consider fitting some reflective foil material to the windows that are exposed to the most sun in the afternoon.
The previous owner of out TT had installed what he calls "limousine tinting" to the windows; although it makes outside somewhat dark, no one can see in and it greatly reduces heat transmission.

I've got a 27' TT with a 13,500 AC and last weekend it got up to 94 degrees. My wife was melting so we fired up the generator and ran the AC on "auto" for about 4 hours and it never cycled or came off of high mode....however it pushed the inside temp down to a very comfortable 69 degrees by late afternoon. By then it was still in the high 80s outside. I was very pleased with the AC. We also had a couple of small battery operated fans running to move the cool air around. My trailer is a Wilderness "Extreme Edition" which I've been told is an option that provided more insulation in the roof and walls. Maybe that helped the AC do a better job?
