Normal
I have an RV edition (crank style & newer than 2017 to get the newer frame/axle improvement) and I purposely bought it for both summer and winter usage. Don't ever leave mine out on the lake unless I am in it, so cant speak to leaving it out there but I do put a small piece of trex decking (leftovers) under several of the corners if Im gonna be out for a long weekend and worried about melt/refreeze. Have never even had the trex stuff freeze in to the point I cant just kick it off the ice and pick it up. I use blocks on the corners/front v in the summer and then just lower each side/front until it is decently level....usually ends up pretty level and doesnt shake a rattle when someone is walking around (blocking at more points helps even more). Nice to have option of bathroom/shower in summer but I will say the air conditioning units on them leave quite a bit to be desired....they don't take much of the edge off on an 80+ degree day.
