Gm made many changes to the 700R4 over the years. Several of them were directed to third and fourth gear, and most of those changes post-date the 1986 model year. A performance rebuild could/should have incorporated those changes but would have cost more vs. a minimum cost generic rebuild.
If you have access to a 1991 700R4 designed for a Diesel app it should bolt right in to your Blazer. You'll need an aftermarket computer or a simple toggle switch to control torque converter lock-up but otherwise the trans will shift itself mechanically/hydraulically
I have to believe those Suburban based mini-school buses weigh in around 7000 pounds, so if the 700R4 trans holds up OK for that it should work for your mini-motor home.
Alternatively, you could rebuild your current trans with all the latest mods.
Whatever you do, Add an aftermarket trans cooler and a trans temp guage.
I've added a pointer to an article discussing the 700R4 below.
