My suggestion: Either look at newer E450s with a 22,000 GCWR and 7500# hitch, or plan on taking an older one to a fabricator to reinforce the rear extension. TorkLift (the hitch maker that does camper tie downs etc) has a motorhome upgrade shop, but you might be able to find something local to you as well.
BTW - Running over 20,000 on the older 10.5" ring gear can cause elevated diff temps. At some point Ford changed to a 10.75" ring gear across the board, and then gave the E450 its 22,000 GCWR. I run as heavy as 25,000 combined but at 22,000 pounds, when it's at or over 100F, I can max out my diff temp at 250F after about 10 miles of pulling a 6% grade.
Thanks for the info - Any idea when Ford went to the 10.75"? Have a little budget constraint that prohibit the newer models.
Thanks
