Well, semi-retirement is just now happening, but am now supporting wife's schedule to assist daughter when granddaughter arrives in July. Then it will be preparing for spending most of September in the Philippines and then back to MY projects. I am looking for a forum that has the Allison transmissions as it's main subject as I need to start the searching in that area. I have solidly decided on using the Allison 6 speed as it will give me 1900 rpm at 65mph with no rear end modifications.

Does anyone have any suggestions on forum(s) for the Allison transmission?

Here is a mileage report by the present owner of the conversion to an LB7 of an FMC motor coach like mine that was previously covered by The Diesel Page. He will be making a 5000 mile trip in September and will do a more complete report at that time. He will record results at different speeds, etc.

"Pulling a 3500lb car at 70mph we got approximately 11.8mpg. Without the car behind, we got about 14.5mpg at varying speeds at mountain elevations.

The project creeeps forward!
