Not sure your towing capacity, I had a 1/2 ton chevy conversion van (1500) and pulled a 2000, 29' 727X ultra light from prowler, we paid 12K new in 2000, only issue we had was the galley hoses got caught on the slide and had to be repaired. I found one on craigs list for 10K same year
2000 27' Prowler Bunkhouse Travel Trailer with Slide
One thing I found is region drives price, in 2001 we moved from Omaha where we bought our RV to Colorado, the same one was selling for 16K at a dealership here. In 2002 we traded it in for a fifth wheel. The bunks are for smaller children, too small really for large teens )we used them for storage when we lived in it for 4 months. Bathroom was a bit small too because the location of the bunks. It slept 8 if you used all of the beds (double from fold down couch, 2 in a queen bed, double for dinette, and two bunks)
Ours had a single slide on the galley side. The ultra light is just over 7' wide, but it was amazing how much extra room the slide out gave (the galley and couch were on the slide). It was just under 4000 and with a load leveling hitch and properly adjusted brake controller, it pulled good and handled well. I did tow it a couple of miles down to a local campground without the load leveler installed and it made a huge difference, steering was real loose and back end of the van was visibly lower.
