so we're still discussing a new TV to replace our rather underpowered but otherwise great V6 dodge Dakota looked at a few pickups, 1/2 ton size with small V8 or high powered V6(ecoboost for example...
We used our '98 E150 to tow a pop up for many years. Towed like "it wasn't even there", even with the smaller V8 (4.6L). After about 10 years, the springs sagged enough that we added an extra leaf.
The only real "small" full size van is the Ford Transit, low roof and regular wheel base. What ever you do, make certain to get the HD trailer tow option. If you are camping in Canada/northern US you probably do not need the rear A/C option. I highly recommend the heaviest tinted rear windows,
