Doug, that's 29% of total weight on the front, or front axle loaded to 83% of its rating. The two bogeys for this are 32%+ of total on front and front loaded 75%+. You meet the 75% but to me the 32% of total is more important because that's a front-to-rear balance. What if a much lighter coach on E450 had only 65% on front but that 65% also represented 40% of total weight? My guess is it would be a good-handling small coach with lots of carrying capacity. Good handling with the right alignment and tire pressures...
I suggested to another OP that he find some weight to load forward and see how it changed. He did, about 500 pounds, and it didn't. Still handled poorly.
