Am I crazy for attempting this??

Why not 4.10s?

with 35's in a towing application. 4.10 is already undergeared for 35s you need at least 4.56s if you want proper, if you want half assed then sure 4.10 but hes also talking about towing so you already want a higher numerical gear to make it easier on you so id say 4.88s

with a 4.10 and 35s while towing your trans will search for OD or converter lockup and the entire towing ability of the truck will be at a struggle

The trans engine are new and trans is non lockup converter but full locked trans with 1650 converter. So I can tow in 4th now. It's a daily driven truck and will do some towing with that camper so a good all around gear would be 4.56 or 4.88?

That your brakes still suck for trying to stop all of that weight. GMT400's are not known for their wonderful brakes.

Trailer has wheel electric brakes

That goes without saying but your putting a lot more faith in trailer brakes than I would feel comfortable with. On the last trip that we took with our Yukon and travel trailer we ran over what looked like a can of beans. No biggie until the next time that I stepped on the brake and 11,800 pounds didn't want to stop. That can hit the back side of the trailer plug and sliced 3 wires. Stuff happens, obviously, but if you plan on pulling more than a time or in the period that you own your truck you might really consider brake upgrades. Gears will help you get going but brakes get you there in one piece.

Very true what kind of brakes did you upgrade to?

I refused to tow the trailer again until I can get our dually back on the road.
