As for me, after fighting tow-vehicle issues most of the year since I went from an open to a 24-ft enclosed, I finally coaxed my old Jeep 5.2L AWD V8 to pull at my desired speeds without overheating by deleting the AC condenser (well after upgrading to HD 3-core rad and cold stat). I never used the AC anyway. I really do love having an SUV as a tow vehicle. Anything larger or less powerful just wouldn't work out for me.

Wow, it would scare me to tow a 24' trailer (even an open one) with a wheelbase as short as a Jeep (any Jeep).
