Well, since 7 months have passed, I had better update this idea:
I ordered and received 1-1/2" spacers from RB3 - Thank You! I've not installed them yet, but believe this will probably be the only mod I do to ready the P5 for Moab. Power steering, a Torque Locker nor shocks are in the budget.
What changed is I am now towing a 28-ft enclosed trailer out to Moab, so there will be room for me to take both the P5 and my 250R. So, my travel budget has been getting tapped for repairs/mods to my truck for the long haul. We leave in 43 days and I am by no means ready to go. This darn job keeps getting in the way of me prepping for the trip!
