When we picked up ours and no electronic door openers or locks we remained in area and got that done at an extra $$. It is a life saver too. Wish the house door was electronic as well but I don't know about new models. You may need an adapter to convert your electric line from 30 to 50 amp... or mine I have adapter to go 50 to 30 in case I don't have full 50 amp service available. a short water hose to work with the macerator might be a consideration. A water pressure gauge to make sure you have decent pressure and not too much at incoming water supply. quick dissolve toilet paper, holding tank treatment ...and the campground in Elkhart is a good stay over for a few days. Things are always needing tweaking. It is easier there than by phone later. Good luck and welcome to the family.
