I've got no doubt the 4L80 is a good trans. It's based on the TH400 which is also excellent as a rugged non-lockup and non OD trans). My 87 diesel 3/4 ton Suburban had over 500K when the 6.2 engine blew to pieces and the TH400 was still fine. Even wore out the rear-axles splines twice, but the trans kept on going - and still is. My son took the Suburban to Colorado, put in a used 6.2 along with a turbo, and still drives it on hunting trips to Wyoming with 33" tires stuck on it.
I've also got an 83 Blazer diesel plow truck with a TH400 - along with a mechanical-modulator. Also been great.
The thing is with this mini-motorhome is . . . I baby it. No towing or beating on it . . . but there's no getting around the fact that it weighs 7000 lbs. and I climb a lot of hills at 60 MPH. If I felt confident that I could build a 700R4 to stand up to that use for 100K I'd do it. I'm already sure the 4L80 and TH400(3L80) can, . . . but it's a lot more money, including the controller, throttle-position sensor I'd have to rig up, etc. So, I'm researching a bit. If I had to tow anything, I'd never consider the 700R4.
Also, if there was a torque converter available for the TH400 with less slippage loss at crusing speed, I might try that also. As I recall, there is a 15% loss all the time, which I'd like to dimenish or eliminate.

Today's Featured Article - Harvestin Corn in Southern Wisconsin: The Early Years - by Pat Browning. In this area of Wisconsin, most crops are raised to support livestock production or dairy herds in various forms. Corn products were harvested for grain, and for ensilage (we always just called it 'silage'). Silo Filling Time On dairy farms back in the 30's and into the first half of the 40's, making of corn silage was done with horses pulling a corn binder producing tied bundles of fresh, sweet-smelling corn plants, nice green leaves with ear; the
