Ok, sorry it took all day but I've been traveling. First thing you need to check out is the Schwintek slides. That's the 2 up in the living room. Run them in and out half a dozen times, watch and listen. They should seal up tight both in and out. Listen for any popping, motors dragging down hard or anything sounding abnormal. The slides should go in and out without a whole lot of effort. You can SEARCH this forum for issues with the Schwintek slides. A lot has been written. Next would be the air conditioners. The ducting on some AC's was terribly done and airflow out the vents is pretty poor. It's actually a pretty easy fix if your handy. SEARCH Air conditioning not working or ducts and you'll find a very thorough thread on these issues. If your tires are still Acuret tires think seriously of changing them NOW. SEARCH Acuret tires or China bombs for threads on this issue. Paint is an issue with the front cap and does have a tendancy to fade. SEARCH paint fading or front cap fading. Other things exist but the slides are the worst. Start with these and let us know if you need more info.
