Bought it new. Full timers. Came with every option including generator. Had a significant list of squawks. Frame was rusting. Drawers needed repairing. Other little stuff that I took care of. I was impressed by the frame strength -- very good. I have been doing many upgrades. We removed the short wall at the foot of the bed. Stupid design. We treated and repainted frame with Por 15 products.(lots of work). I added 7 inches of isopoly insulation boards under front half of trailer in large empty spaces. (R40 anyone?) Upgraded to Moryde IS with disc brakes. (They are the best.) Later found water freezing up at 20 degrees F. There was about 15 feet of un-insulated vinyl hose from fresh water tank to pump. Duhh. That was freezing up. Put heat tape on it. Then insulated the heck out of it. Removed back half coplast underbelly, installed extra Ultra Heat pads on tanks and dump valves. Added lot's of pink insulation everywhere and closed it up with 2 to 4 inches of isopoly insulation boards under tanks and enclosed full underbelly. Used eternabond to seal everything up. Painted it with black enamel. Put lots of insulation behind from headboard of bed. Was very cold area lacking much insulation. Plastic film over the dual pane windows. Door blanket over door. Solar, large screen TV and satellite too. 600 ah Lithium battery bank, inverter, b to b charger. Anyway, this is now the warmest, tightest, most comfortable trailer i have every owned. I do not skirt it because we travel a lot. It is 6 degrees as i write this. 80 degrees inside trailer. (We have spent most of our lives in the tropics and like it very warm.) One small electric space heater and one dehumidifier keeping it nice and warm and dry. At this temp of 6, once every two hours or so, the lp furnace will cycle for just a few minutes. Above 10 degrees no lp furnace needed at all. Attention to detail, added lots of insulation, and a good design to start with. I think (guess) this trailer is good to 30 below now. I will test it to -12 F below in two nights. It tows like a dream. Have pulled it is 50 MPH crosswinds with F250 -- no problem, no sway. Coated outside with nano ceramic coating. Bugs don't stick. Have boondocks for three weeks at a time in it. (Tank size sets the outside limit without blueboy and water bladder backup.) Can access everything with slide in. Great for rest area naps. It is a heavy trailer. Well built but they could put more attention to details. Overall, I won't trade this trailer for anything I else I have seen. With my many mods, it is my castle on wheels and I love it. Would not trade it for Airstream or any other trailer that is 27 feet. Took some work, and some money, but I think this unit now is the best. It is NOT for sale!
