Gear Vendor is a very nice option if you can grab a used one. They are a hard hit new...From what I understand the unit itself is universal then you can buy whatever adapter you need from GV.

I'm on the hunt around here (Western Washington) for a Gear Vendors unit-one yard I know of in particular has at least a dozen old Dodge chassis motorhomes, so I think with a little patience and luck I can get one for about $400. Of course, I have to pull it, but it makes it worth it!

It will probably be tomorrow or next week before I can get out to that particular yard- it is in the eastern part of Snohomish County

Okay- spoke with Gear Vendors. The motorhomes have their own 'special' casting due to the fact that the factory parking brake set-up gets replaced by a Bendix unit. You can adapt one from a P/U 727 trans, but it takes a bunch of parts and work that would run in the ball park of $2K. Finding one on a motorhome? Odds are low since the Dodge motorhome unit is the one they've sold the least of, but it could happen...\n\nYeah, I'm going to put out "Feelers" and go look a little

I would not be to concerned about the driveshaft brake. It's pretty useless anyway. At best it might stop you at about 2 mph.\nI chock my wheels if parked on an incline(which for an RV'er is taboo anyway)

OK Gang...\nNow I'm obsessed with the idea of an Eaton 2 speed axle. I've done some digging around, and have read that the "medium duty" axles that they made for box type trucks and "light" dump trucks were available starting with a 3.55 x 4.33 gear combination.\n\nI suppose that one could change ring and pinion gears in those to make a useable gear set for what an individual might need, concerning the area that they live in/ travel to.\n\nI wanna find something in the range of 3.55 and 4.56 or so... I figure those would be ideal for the fat areas of Ohio, Michigan, Illinois, etc... and the 4.56 would do just right in West VA, PA, Delaware, etc...\n\nAnyone know of a decent truck boneyard?\n\nCHEERS!\nSlick

when i picked up my Travco last month i thought of the manual two speed rear end...they are out there on a lot of old trucks and bus's.\nfortunately my boss was scraping his 1980 service truck and it just happened to have an under/over drive unit so i grabbed it. 8-) \nIt sits as a nice stand alone unit so i think i am going to look at mounding it back by the rear end.\n\n\nand there must be a few of these units kicking around as well.\nhttp://hone-o-drive.com/wp-content/uploads/2013/10/Shelby_Hone_Original_Brochure_and_Order_Sheet.pdf

when you look at them they might be a bit light duty. :shock:\nbut i wonder if the company went on to make heavier units.\nthis is the one i got from work...i will just make/get a spline shaft with universal joint couple on it for the female end. 8-) \n\nImage
