I flat tow my sammy with my Ford Ranger, and it does great. I have the HO 4.0 l v-6, 5 speed auto, 4 x 4 with 4.10's and posi. It down right scoots down the highway, the last trip I was running circles around 2 Suburbans pulling heeps and a F250 pulling a bronco. I could run cruise at 75 with no problems and they could barly hold 65 on a little grade.
BTW the Ranger is up for sale, Because I got a new company truck. The Ranger is an 01 XLT with 90,000 mi. looking for about $9,000 for it.
