This question is for those that have a Ford V10 in a class A. I have a 2007 Allergo 32BA with the Ford V10 that only has 36,000 miles on it & I took it to mountains of Western NC this week, and it see...
40 MPH with a dinghy is typical of what we just did in the mountainous section of I-70 in CO. I was trying to keep the RPM at 4200 but based on posts maybe 4700 would have been better. Worst grade was this trip I-70 from Dillon to Eisenhower Tunnel, 12 miles of 6%. Don’t like straining the tranny like that as it was making some strange whining sounds the last mile or so (5 speed Torqshift). May unhitch the dinghy if we ever do that grade again.
