how long do you keep

we keep changing trailers cause our family and finances keep changing. Early days in '80's needed bunks for the 3 kids. Mom and I wanted walk around bed but hard to find with bunks in only 24-26 feet (was towing with the 65 Chevy Van so length and weight was important restriction). After kids left home, moved up to 30' Arctic Fox towed by 454 Suburban, yay, walk around bed! 2008, had to sell it all, back to the 65 Van for towing (still have it, it still can tow). '85 22' Wilderness, no bed, no air. Now grandson wants to camp with us so '04 Tahoe, bunk beds, but double bed only 48" wide. Buy '94 Suburban to tow with, so now a '05 26' TrailCruiser with walk around queen bed, yay! No bunks so grandson relegated to a tent, outside. Hopefully this one will last us more than a couple of years.
