i towed a bunch of 931s w/ tankers full of fuel around the MSR the night of the invasion in '03; and it does pretty well. i have also driven a fully laden HET just for S&G's.
i couldn't imagine a single 984 pulling
the fully laden HET. seems like it must have taken days for it to get up to any kind of speed over 20 mph...
don't get me wrong, the HEMTT is a bad mo-fugger, but is seriously lacking in the power-plant department considering the given GVWR. let alone when coupled to
220,000 lbs.
my HEMTT would have a 600hp Cat in 'er... plus Pistburg Power mods.
