Is it worth regearing my tow rig?
I recently bought a new travel trailer and a used truck to use as the tow vehicle. When I bought the truck I was told it had a 3.73 rear diff... anyhow after some investigation it has the 3.42. That...

Not to be a buster on this idea.......Depending upon the gear ring size, going lower than a 4.10 to 4.56 or even a 4.88, may put the teeth too small. So yes, you get use of OD towing. BUT, if you stomp on the go pedal in 1st gear, you may break the R&P teeth! If you have an 8.5" or smaller setup. I would not go smaller than a 4.10. If you have at least a 9.5, then a 4.56 may be the largest you want to go. I really doubt you have one of the 10.5 or larger ring gear setups with a 1500, those, into the 5.xx would be doable.
Also going lower, you may need to change out the axel shaft itself, as the current setup may not handle lower gear sets too! A new 9.5 or larger RP from a 2500 may be in order. Now you have to change out the 8 lug to a 6......any way, I'm going to quit typing, as some of this may be an issue, or it may not!
Just throwing another monkey wrench or 2 or 3 into the thought pattern here!

I don't think that it would be an issue really. In the offroad world a Dana 44 can take 35" tires and a crawl ratio of over 100:1 and not break teeth...being stomped on to climb something all the time. That's WAY more torque than a street driven truck towing, and the D44 is a lighter axle than a half ton has.
