Not to save gas, as there are still a lot of dead dinosaurs down there for me to burn through, but I like the reputation of the 727 transmission. Thinking the O/D would just make it nicer to drive for towing on the road, and if I save gas in the process, ok.....and working on that angle separately.
We currently are using my dads 16 ft Scamp camper, which the GW will be pulling when ready, which is less weight than most flatbed trailers empty.
So when I get the GW road worthy and driving, will see how it performs, and where improvements are needed.
Seems as with most add on devices for these old rigs, to make them more like our modern vehicles we are spoiled with, anything costs thousands of dollars. At the stage of my build, watching what everyone else is doing, to try and get my money best spent when the time comes.
Thanks for feedback, and keep burning the dinosaurs
