I would have figured this having been asked many times but I couldn't find anything. My girlfriend has decided to let her son and family move into her house because she no longer wants to deal with it and decided a medium sized 5er would fill the bill. What we want to know is what brands tend to be most trouble free for leakage, has good quality appliances as in furnace, ac, refer etc. It will probably never move but should be comfortable in weather to low twenties only occasionally with some winters only in high twenties. Of course this is a somewhat opinionated issue but what have you had good or bad luck with? She has a full 50amp RV hookup already on her property so is already for hookup. Thanks for the help.
