inverter, 2-160 watt overlander solar panels, in-line 30 amp surge protector, tire pressure monitor, Blue Ox towing system, upgraded the digital tv antenna, installed satellite-ready radio, added mount & tv to bedroom. I replaced the mattress with decent one that has an oversized topper on it, so the mattress hasn't been directly slept on. The unit received the EcoRvPro appearance protection. The unit currently has about 19,400 miles on, it is in excellent shape. Always stored indoors and engine maintained very well. Length gets you into state and US campgrounds.
