If I'd of known a couple days ago I would have been all over that, and I agree all the camper specials I've been around had 4.10's. This differential is in pretty good shape it seems and I can always use the springs off of it. I don't remember where you are at I'll shoot you a quick PM and we will see how close we are. Do you know what you'd want for the rear end?
Right, and from what I have gathered from Nick, and my local tranny guy Dan, that's about right. The biggest thing that kills overdrive as far as towing is if there is enough load to cause it to slip.
However and I mean no offence to anyone but this in not flatlandia here. There and mountain passes and where there aren't mountain passes there are ridges and hills. One example I like to give is coming back from west of the tri-cities then just after Yakima there are three ridges that I have to pull the highest is Manastash ridge at a crest of 2,600 feet the grade is steeper then the actual mountain pass we'll get to in a moment. So there are three ridges and then before getting to Snoqualmie pass which is a longer but more gentle climb there's about 40 miles of relatively flat road and I might cautiously trust overdrive on that 40 miles. But that just gives a little bit of info about the land out here. It's just not very flat so overdrive while towing would be of very limited use I would think.
I'm not saying no to the use of overdrive I'm just doubtful there would be a lot of use for it out here.
Ok, I wasn't sure what your goal was with figuring the desired rpm in 3rd gear.
So let me ask you this, how often do you find yourself using overdrive currently? Do you think you will be able to use it more often with steeper gears?
What about gearing it really steep, like 4.88's or 5:13's and using overdrive as a "normal" selection?
