We are in our 70s. We need a vehicle that will work for an around-town car about 90% of the time and tow for the rest. We can't afford, nor do we really need, a big muscle truck. We don't haul stuff around, except ourselves and the normal stuff townies carry in the course of their lives - no drywall, or heavy machinery, or even heavy tenting gear. What we do need is a reliable truck that can pull our ultra-lite TT with room for us and our kayaks, and once in a blue moon, maybe the grands. A truck that won't fill up the parking lot at Safeway. Everything we need to haul will fit into the back seat of the cab. So no, there's no way we're going to try to afford a bigger truck than a half-ton.
We have a good friend, a very experienced TT guy whose on his 5th one, a 22' Airstream, in 40 years, who tows with SUVs. His current one is an MB diesel and he's thrilled with it. Tons more torque than he found on any other TV, rated at 7000#, and he carries two adults, one big dog, and two kayaks without even knowing he's pulling anything.
