We started with a GMC Sonoma. Added a trans cooler to start. It had the Vortec V6 which handled the trailer nicely. The cab was just too small to travel with 2 adults and was on the light side for a loaded trailer and all the "stuff" we carried.
Moved to a Chevy Trailblazer with the Vortec V6, and factory tow package. Nice comfortable all around vehicle for towing our 17' SD. Still needed more room for "stuff" and a bit more comfort.
Presently towing with 2011 Chevy Silverado LTZ crew cab with the 5.4 liter V8. Factory tow package, bed cover and it provided very comfortable creature comfort. Tows the trailer as though it isn't back there. Gas mileage is 15 MPG towing at interstate speeds.
We used to tow with my little 2004 Nissan Frontier, with its 3.3 L lawn mower engine. I even towed the trailer home from Texas with it. While it worked okay on the flats or small inclines, some of the "out west" roads and passes can be downright scarily slow pulling those 7% + grades that run on for several miles at a stretch. For example, I would start up the Dougherty Slide, (HWY 140 in Oregon,) for example and wondered if I'd even make it to the top, (at over 7,000',) or going up the 14% grade south of French Glen, OR as well. My poor little truck reminded me of the kids book "The Little Engine That Could," saying to itself "I think I can, I think I can," all the way up. Surprised the poor little guy didn't puke his connecting rods up on some of those trips.
Now we have, (I should say my wife has.) a (new when she bought it) 2016 V-8 Chevy Silverado Crew Cab with tow package, 4x4, full bed canopy, and it tows like there's nothing even back there. We don't use the WDH spring bars with it anymore, but do use the sway bar. We also get 15+ mpg towing with it, and it will accelerate going up those long grades without even breaking a sweat. My old Frontier only got 10~11 mpg if I didn't have to put my foot into it too much.
Frankly, I would never even consider towing with some of the truly "minimal" tow vehicles I've seen some people use.
