Even the turbo'd civvie one that I had was a dog. I had an enclosed trailer for the "nuclear golf cart" that grossed at maybe 4K. Even the smallest inclines bogged it down the 35 MPH.

The HMMWV's that we had that weren't the factory up-armors were total pigs. Even after thes suspension and electrical mod's, that NA 6.5L just couldn't move 13K lbs of truck very well.

I usually ended up taking the '89 Suburban that we "acquired".
