Obviously some more digging is required. May have to go with a 2 speed and just lock it into high range or tighten up the ratio split to give it some advantage from a standing stop. Going to have to get under the crewcab with a tape measure and see how much room I have for another diff in the front now that you have added that issue to the list
Thank again

Clearly, there are lots of vehicles out there with low pinion front diffs - but for the most part they are either part-time or at least take a lesser portion of the load for full-time use.

For whatever this is worth...
A few years ago I was thinking about swapping a 6.5TD into one of the 1st gen toronados (1966-68 or so), but didn't like the 3 spd non-lockup transaxle.
I found that they did offer a 4-spd O.D. version from 1982-1985, with a lockup TC (I assume). Not sure if it could be built strong enough for a 6.5/motorhome use....Seems like there are some still out there, according to car-part.com.

Before embarking on the subframe swap idea, I talked to a guy in California who is the guru of these transmissions about the 4 sp., lockup version. He was less than complimentary about them, saying they failed even with the V6 powerplants.
If memory serves, I believe he said it was based on the old thm200r4. Gear ratios in lower gears were great but would need a butt load of cash to strengthen them up to take the torque and even then, their lifespan would be suspect. Again old tech with limited parts availability.
Thanks.
