I would recommend some sort of leveling system whether it be factory or aftermarket. I have a three axle fiver and it was not easy to get all three wheels up on blocks to level side to side. now it's the push of button. The other advantage is it makes the coach much more stable with four or six points on the ground. As for the generator, since most of our camping is Boondocking, I would not be without one. The gennie is in it's own compartment and I still have 3' x 2.5' of unobstructed storage that goes all the way through to other side of trailer. My next investment is solar. JMHO
