If it's 2WD are you planning on towing it backwards?????
If it's a 4WD then a dolly won't help you, but if you can select "N" (Neutral) on the transfer case you can flat tow with no dolly.
From the 2004 Owner's Manual
here, section 160.
"4HI
4 Wheel Drive High Range - Locks the transfer case inter-axle differential. Forces front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only.
4LO
4 Wheel Drive Low Range - Low speed 4 wheel drive.
Locks the transfer case inter-axle differential. Forces the front and rear wheels to rotate at the same speed.
Additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h).
N
Neutral - Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. See Recreational Towing for more information.
Shifting Procedure - NV244 Transfer Case NOTE: If any of the requirements to select a new transfer case position have not been met, the transfer case will not shift.The indicator light for the previous position will remain ON and the newly selected position indicator light will continue to flash until all the requirements for the selected position have been met. To retry a shift:
return the control knob back to the original position, make certain all shift requirements have been met, wait five (5) seconds and try the shift again."
