My last 5er was an 05 , 275 Topaz , EEE. Solid , warm , dependable and built for the long haul. In 5years from new , tires and batteries were the only repairs, and those were in the last year of ownership so , I guess you could consider them maintenance at that point. 70,000 kilometers towed.( 45,000 miles )
Triple EEE is still in business, but I'm not sure how many product lines they are producing at this time.
Boondocked in my Topaz, at -27 degrees and was comfortable.
