1/2 ton towable FW

Before our current Motorhome, we towed a, 1999 25 ft. Jayco 5th wheel with no slides with 2 different half-ton Chevys for 10 years. It worked out fine but I always said that I wouldn't want any more weight; not even a few hundred pounds. For the life of me, I can't figure out why the manufacturers don't make more truly half-ton towable 5th wheels in the 25 to 27 ft. range but they don't. There are plenty in the 30-32 ft. range but they are really too heavy for the average half-ton. Sure it might work if you have a newer half-ton equipped with the biggest motor, heavy duty suspension, etc. but most half-ton aren't. Oh, and don't pay any attention to salesmen. Fully research it yourself and don't tow any more than 80 or 90% of the truck's advertised capacity.
