Anyone make a mistake buying first MH ?

We just bought our first MH, 36' 2 slides, Allegro. Had one growing up as a kid, talked my husband into buying one, kids gone, hate flying hate airport security more! Want my dogs to be with us to... Want this to be a good experience as newly retired people. Went to pick up our coach in Palm Desert and had cab air conditioning problem and awning "sticking", they had to take it to Colton to fix, supposedly delivering tomorrow.....already having second thoughts, to late though. Now having too much time thinking about how hard this might be to drive!
Help.......need some positive stories on first timing!
