I personally know at least three people who tried to make a go of it with a lightweight 5th wheel and non-HD 15-series (1/2 ton, F150, 1500, Tundra, etc.) trucks. Suffice it to say, when it came time to upgrade, they didn't buy 5th wheel again.
Sure, these lightweight 5th wheels are 1/2 ton towable, and are even within the ratings, if all the stars are aligned: The right truck, not too much stuff, not too many people, loaded perfectly... Real people don't travel that way.
Sure it works, nothing falls off, and nobody dies, but will you like driving it or will you be spending every trip wishing you had more?
The RV and truck dealers *LOVE* it when they send you away with a rig that will have you wishing for more in a year or two. They figure you'll come back and upgrade.
