If it has truly has the Full Banks system, Headers,FF muffler CAI, I think you would be able to climb hills better than most MH's because of the HP to wt ratio even with out the better 5 or 6 speed Allison. Nada high retail is $26 k for that model. I would test drive it and look it over good. What does it weight? and how much CCC to you have? See what kind of acceleration you get on a flat from 40-60 mph if it is in the 10-12 sec range and every thing else looks good it would go to the top of my list.

It pulled insane up a very steep grade near the dealership. I accelerated to 45 going uphill and then it kind of flattened out but that was when the grade got even steeper. I think I found a keeper

40-60 mph times on a flat is a good test because you might not have the same slope hill to try out the various MH's that you are trying to evaluate. More over most people report a "seat of the pants dyno" which my be more throttle noise but numbers don't lie. Good luck in your search. Don't be too quick to buy the first one you like (like I did) but look at many of the size,make, floor plan, and chassis that you like. Unless it is priced too low it will still be there when it's time to make a decision.

In the VIN number, look at the sixth digit.
5 is Motorhome P chassis.
6 is W22 motorhome chassis
VIN 7 digit should be a 7 for motorhome
VIN 8th digit is engine code.
G is for 8.1
J is for 7.4
I do not see anything that would indicate the transmission other then all P chassis came with GM tranny and all w series came with allison LCT 1000.

Thanks! It has the 8.1 and the Allison woo-hoo!

There should also be a switch on the dash to turn the OD ON/Off. W20/22 Chassis and Alison Trans.

Check out "IRV2.com, then the Workhorse chassis forum. Their are several knowledgeable guys who can identify your transmission

Depends on chassis.
P series 1999-2002 have a 4L80-E 4 speed, 2003 has the 4L85-E
W series has the Allison LCT 1000 5 speed.

Is there a way I can tell from the VIN? I'm pretty sure its the 5 speed as on the tree it has 1 2 3 and then D with an O around it, so I am assuming that 4 is D and the O is 5 / overdrive?

I would assume that if it is a 4 speed it would say 1 2 D then an O around that?

Simple answer:

If the tranny has a small spin on oil filter at the front of the pan, it is an Allison... :)
