A couple of years ago we were at a RV show and saw a propane tank on a slideout tray. I don’t remember what brand fifth wheel it was, but it was a high end unit. I remember thinking at the time how nice it would be to have that feature.
A full 30# propane bottle weighs about 55 pounds and at my age, with my back, I don’t relish with task of getting a full bottle back into its cubbyhole.
Maybe Wildcat could offer an optional package with propane slideouts and a battery cutoff switch and call it the Crabby Old Man and Bad Back option. I’m not proud, I’d order it.
