Adequate is a relative term. At a long 6% grade, the new V10 and 6 speed set-up reportedly will get down to about 45mph.
There will be an obvious difference to how a 40' RV with a rear engine CAT would crest the same hill, but these Ford chassis have no problem hauling the rated loads.
A 1,300lb golf cart is less weight than 2 full dressed motorcycles, so from personal experience, it would work very well.
