What ONE feature do you really like/want in your next RV ?

We already have it....only took 25 years and several 5th wheels to get here! Here’s the list: Comfortable to a -20 F, dual ac’s, large solar panel system, 6 batteries, hydraulic disc brakes, Bigfoot Auto Leveling, Stackable washer and dryer, 2 Thermostatically controlled Fantastic Fans, 2 inverters ( one a 2000 for most of the unit, and an 800 dedicated for our 5.0 cu ft. chest freezer), dual pane windows, triple axle with 17.5” rims/tires, all LED lighting, added a 12 volt automotive radio/Sirius XM (energy conservation when boondocking), and installed an 12 volt automotive radio/SiriusXM for energy conservation when boondocking. Want to get full skirting for the long winter boondocking trips (help conserve propane)! That ‘bout sums it up! memtb
