33's, 2.7s, gears, waiting, wheeling and the like

Howdy,

Just want some opinions for those with 2.7 and offroading experience. Right now I am on 32s in my little 4-banger (actually not so little since its a bloated 2nd gen pig). I wheel a good deal and fairly difficult terrain. I can get where I want to go, but would like to upgrade.

Here is the thing:
I need new tires. I do plan on re-gearing next spring, but the funds won't be there until then. Has anyone wheeled with a 2.7 manual and 33s without regearing? I realize that on road I will lose power (5th go bye-bye), but how is it wheeling with this combo? I have some runs I need to lead this summer and I would hate to be struggling too much. Keep in mind, I am heavy. Full skids, sliders bumper and winch.

Thanks in advance for TW wisdom!
