New 21BHS - Mods/purchases before our first trip?

[Merlin]

In the faint hope of keeping the camper a bit cooler going down the road, so it isn't so toasty hot when arriving at a campsite, we leave the 2 roof vents open when traveling. I installed the Maxxair vent covers so we can keep the vents open 24/7 if needed. I realize the vents don't do much for circulation when the fans are off (and they are off when we are going down the road), but maybe some air goes in/out from the Bernoulli effect at 55 mph?

And ditto on the Andersen levelers. Easy to use, provide precise leveling, and make their own chocks for the wheels on one side of the trailer. Just cut off a couple inches (of both) to fit the double axle trailers.

We have the MaxxAir2 vent covers as well, but choose not to leave our vents open while towing due to the dust that we seemed to pick up in the trailer as we traveled down the roads. But we do like the MaxxAir vent covers because we have our vents open quite a bit while at our campsites!
