Just wanted to update my previous (November) remarks on the Diesel swap and maybe modify the conclusions I'd made a bit.
Over the last approximately 1900 miles it seems the combination has been 'dialed in' a bit more and the results have been pretty impressive. The mileage has definitely increased and the overall performance is better. A run from Albuquerque to Kingman AZ netted 15.95 mpg running into a head wind running 63/64 mph. On to Las Vegas and near 100 miles of Las Vegas urban driving, down to San Diego and over to Quartzsite managed 14+ (nice to carry 75 gallons and fill at the cheaper locations). The coach ran up Baker grade at 60 mph in 3rd gear. A direct comparison to the old motor 403/3.55 geared coach was 40 mph in second. If you aren't familiar with Baker grade it has been the death of many an RV. A six percent grade that peaks out about 4700' it's probably one of the 10 toughest hills in the west.
There still is a little tuning to be done but 15+ mpg and the performance of the combo really brings a smile to my old face. Ain't it fun.
Hal
