rear end swap
I want to swap the rear end on my truck (99 dodge 2500 2wd 360 v-8) for one with 4.11 gears. Does anyone know of a cross reference that I can use to find what other vehicles have the same rear end as...

I don't see where you state what ratio you have now, so I'll go with a 3.55 as it was the standard on trucks from Dodge of that era. I would do the swap, but probably with new ring and pinion hardware and bearings etc. Used parts are crazy high around here at least, so buying a whole rear may not save much if anything. Also, you will never want to go back to the 3.55s. I have swapped ratios several times on my gassers and find that my towing mileage increases without much effect on empty mileage. The 4.10s put my trucks into the power band for pulling hills better loaded as well as the 50/55 mph zones in 3rd with the converter locked, and allowed OD loaded on the interstates.
Ditto this.
I run a '02 4.7 1500 and went from a 3.55 to a 4.10 and this is exactly what it did for me. With the 3.55 the transmission was constantly up/down shifting. The 4.10 allowed it to stay in a particular gear within the power band. My engine/tranny combo is probably quite different from yours but it allowed me to tow for 8 years with this truck.....
