the screens on the crank out windows let every bug in the campground in. they do not fit the windows correctly We have one *** of a time getting our door shut, must slam it hard every time and when we first got this camper there were nights we could not even shut or lock our door, very unhappy that we have to run air all the time and leave windows closed. fresh air would be nice without bugs of all types. sliding door in bed room need guides so they run true and not bang opening and closing them the retailer was out 6 times making things work until we had to move on not happy with quality of this $100,000.00 camper User's recommendation: before you take it off the lot make sure everything is as it is suppose to be. finished and working.
