Keeping 5th Wheel cool in Texas sun

One of the benefits of slide toppers is they shade the top of the slides and that really help prevent heat from building up on the slides.

This would cure your problems!

We are also in south TX with limited shade in the afternoon. We purchased the pillow vent cushions for the vents and reflective insulation for windows that face the sun. We also going to insulate all cabinets, and shirt closets. Also, do some caulking inside as we noticed our outside storage compartments were cool when we opened them. During the hottest part of the afternoon, we go to the pool, happy hour, or do our shopping.

Our 2nd was a class A with 2 a/c's we didn't have to put the shields up to keep it cool.

Most likely the Class A had dual-pane windows plus A's have better insulation.

We camp quite a bit in the Arizona desert during the summer (boating at the lake, triple digits). I have 3 air conditioners and we stay cool. We have all ceiling vents plugged with one of those thick cushions from Camping World. Next we cover the windows that face the sun.

One problem I had with my trailer was lousy build quality in that there was greatly reduced air-flow through the A/C due to poor construction. I had to re-tape the ceiling A/C vents due to leakage into the ceiling, re-do the plenum taping under the fully-ducted A/C, and open up the fully-ducted return air intakes. Now that air is moving we are keeping much, much cooler.

Keep in mind that our trailers have lousy insulation to begin with then add in single pane windows and we are fighting a loosing battle in the summer heat.

There is a RV park by Azle Texas that has carports to keep the sun off, would prevent hail damage as well.

I would try to move to under a shade tree. If your hot now wait till summer gets here.

When in Texas (or Oklahoma or Kansas) in the summer, parked in the sun, I've come to accept that anything under 90 F is"cool." That's with 30 feet of house and one 15K A/C unit. When the A/C is taking in that 90 F air, it is pumping it back out of the vents at 70-75, so I sit under a vent.

2 A/Cs do better than one; high end motorcoaches in 40-45 foot range may have three to five 11K to 13.5K units to better handle solar heat loads and manage zone cooling.

Solar heat loads can be hard on RVs. Parked in my driveway on a 80 F day in full sunlight, all closed up the air in my RV can reach 100 F within two hours. That's not as bad as my dark gray car, which can get over 140 F in 30 minutes, on an 80 degree day. At least with the RV I can open the windows, run the vent fan, and pull in that warm outside aur to help cool the inside.

Summertime, I seek campsites under trees, for at least some partial shade. If the outside temperature is much under 85, and I have to be in the sun, I'll open up to the outside rather than try cool a solar oven with an inadequate mechanical A/C. I know a few other RV campers who will just stay outside under an awning, because that's more comfortable than being in a closed up hot box.

Can you move to shade?

Otherwise the only thing you can do is keep the windows and skylights covered.

Block every skylight and that stupid door window with reflectix
