Thanks guys. I did like my '95 but when the torque converter went, it took 3 weeks and over 500 pages to locate the correct one, rebuilt in Atlanta - 21 spline and 14", only 400 made. After I put it back together, the tc apparently took out the tranny despite what the tranny shop guy thought. Suzanne used a stool on a rope to get in and out of Big Blue. It's still in town, but in four years has had four owners and five trannys :(. Still my favorite outside of the Dakotas. Those with the 318 would handle it. Diesels are fine, I have driven and worked on school buses.
The trailer is 10'6" PLUS over a foot for the AC, so I count 12' for overpasses. It's 3200lbs. loaded; our stuff weighs 80 or so lbs, the groceries about 20, 150 lbs for a full gas tank, about 500 lbs for the two of us. Cat scale at Kwik Star said 3986 when truck weight was deducted. That's how I figure 4000 as an average.
From what I've read, newer trucks - even small ones - get better mpg not towing but same towing. I'm just open to possibilities. Blazers might tow nice, but can they stop? The '99 Dakota V6 might have managed with lower gearing, the '92 extended Dakota SLT with the Shelby 318 towed a 4500 lb rig for a coworker, but after I bought it I found a year in the frame was rusting through just behind the front suspension - a shame, nice truck otherwise. I'm just looking to see if there's better choices before I need to locate or overhaul a new vehicle. I'm not opposed to an old sedan or wagon but the height may be an issue.
