I'm kinda confused on what exactly your question is, but it kinda sounds like you are asking should you go DRW or SRW on this, or maybe you are asking can you swap tires from another 8-lug onto this to drive it home. Here is my response which may or may not answer your question (if I've interpreted your question correctly):
You have a DRW front axle and an SRW rear axle on that truck as it sits now. If you have SRW offset wheels and tires, the rear will work fine for the rear to get it home, but the front likely won't clear right to drive it home for two hours. You need to swap some new tires on the front DRW wheels to make the drive home. Or find a set on some DRW wheel already that you borrow or buy cheap for now. Check Craigslist as there are often sets floating around (just make sure they are 8x6.5 bolt pattern). If you had a DRW axle on the back you could drive just fine on single wheels per side instead of having two per side. That's not an issue at all. Your cheapest option right now (assuming the gear ratios are the same front to back) would likely be to swap SRW hubs on the front axle. Probably set you back $500-$600 if you do the labor. Maybe more if you go ahead and replace bearings, etc. You're going to need new rotors up front as well since I'm pretty sure they are different on the SRW than they are on the DRW. Hope that helps.
