I'm working with an 04 police package Expy XLT 4WD.
I've been looking everywhere, haven't found good answers. I have a bracket to put the spare on the front (police package) grill guard, but I don't like the leverage it has on the mounts. I'm not willing to pay the large costs for the rear swingout carriers I've found. I'm considering putting it on top (with a lock) - it'll be well within the 250 lb top weight limit, and easily accessible when needed. it will be an air drag problem, and thus cost gas.
I can't find a snorkel kit anywhere, I think I will wind up making one.
putting an aux fuel tank in place of the current spare mount is exactly what I intend to do, but good luck finding such a tank. I'm thinking the marine fabricators will be my go to when I'm ready. they make custom tanks for any application.
