Cooling the cab
Driving my class A Newmar Canyon Star in the Texas 90 -100 degree+ heat leaves a lot to be desired with regard to cooling the cab. Heaven forbid if you're driving into the sun! The dash air on max "meets spec" and running the gen with the 2 roof air, keeps the back comfortable. Placing a ac fan just behind the dog house pushing the air to the cab helps some but there has to be a better way. Has anyone installed a cab curtain behind the driver & passenger seat? If so, is the dash air enough or is roof air needed too? What about reflective film on the top half of the windshield? Would like to hear about others deal with keeping the cab cool.

Gotta love Texas. I'd shut down any vents in back and close it off as much as you can. There's probably some value in getting some circulating air around the driver - IE a fan.
Some people have luck with those clear UV-filters that go on the windows.

I constructed a lightweight material curtain to go across behind the front seating area (In a previous motorhome I owned). Although the material had very little R value, it cuts down air transfer between front and back. The dash air was able to keep the front much cooler with the curtain closed.
I have since learned to go to higher altitudes or northern latitudes to solve heat problem.

This is what I installed. My wife found these cloth shower curtains so I ordered the track from a class c which was $12 and slides for curtains which was $20 for 2 packs. This is the first trip with them and they work great. Blocks out all light when it is dark out and grandkids wants to play WII and with the one vent from ac keeps it nice and if you turn on the dash ac it will freeze you out.

We installed room darkening curtains behind our seats. And yes we do notice a difference in keeping the cab cooler.

When we had our Monaco Diplomat, I bought a spring loaded shower rod and a clear plastic shower curtain. I hung the curtain up behind the driver/passenger seats while driving in hot weather. It worked well, allowed you to see in the back and had a split so you could pass through.
I also ran a ceiling vent to draw hot air off of the ceiling.

The one I put in is also 2 curtains so you can go through the center. Now I can see why class c has these.

Great ideas from all. I think I'll rig up a curtain. Thanks

Installed a curtain many years ago. Just went through TX this week at 100 degrees. Stayed cool the whole way. Turned coach air on only 1/2 hour before stopping so coach was cool for lunch, etc.

I just installed a transverse rod with shower curtains on it. Behind the driver and passenger seats. Going to try it out Wed for a week long trip to a lake.

Haven't had a problem keeping the "cab" aqrea cool with the dash air, at least not yet. In case we do have a problem I wonder if lowering the bed would be a help since we have a 2015 Thor ACE. As long as we remember not to stand up it is driveable with the bed down. Just a thought, Jim.

The curtain also works well to retain heat from the dash heater for winter time travel. I installed one in our motorhome last year for a winter trip to California, and was pleased by the results.

Installed closet rod retainers with a one inch dowel, then found thermal curtains and hung them behind driver's and passenger's seats. Works on both ends...cooler in summer and warmer when the temps go the other way.

I'll add that no matter how well the shower rod with curtains worked, we learned to fire up the roof A/C about half an hour before checking in and let it run while we register.
