I don't think you desperately need 5.29s with 33s and especially with 32s.

Remember, most trucks, including automatics only came with 4.56s with 31s, so you're ahead of the game with 4.88s, plus you have more power than a 22RE.

I would try running the 4.88s with 32s or 33s first and then decide if its really worth the money and hassle.
