Your user name is pretty darn close to mine. I'de say go with 4.30's or 4.56's.

you should drop down to 4.30's it will be the closest gear to get you back to stock....

4.30 would work but considering the extra weight and rolling resitance on the 37's and the fact that you tow 10000 # you should go with the 4.56's. If it was my truck that is what I would do.
