Re-engine a class A

[Tom_Barb]

What would be a close guess as to what it would cost to put a different engine in a big coach.

for example a 8.3 ISC or ISX maybe a 350 cat.

Rather than new or crate engine. Look into used ones. COLAW inear Springfield, MO will quote a price on most anything.

VERY unusual. Normally, it is the EXHAUST manifold that cracks???

Off the subject, but just curious: Wolfe, are you without an RV now?

550 Cat rebuild in the Yukon will set you back $60 grand, just to stay away from all this electronic garbage that is out there, but your life can depend on it when a sensor goes south when it's -50 0n the Demster Hwy. Well worth it. A friend up there told me if the company wanted him to buy a new truck, he would quit driving, been hauling to Inuvik for 35 yrs.

I’ve bought low miles (less tha 50K) ISC and mechanicall 8.3 engines for $5000. Put the ISC in a truck instead of rebuilding the engine in it...much cheaper. Add another $4-5,000 to swap so still less than half of a rebuild. I still have the 8.3 as I sold the truck it was the spare for. Good used engines are out there but you have to search and it can take months of searching.

Well that’s kind of my experience being around FLORIDA. My maintenance guy has a two man shop, $90/hr for RVs cheaper for trucks.. Nice shop, AC, pit. We are construction town around here. We shoot the poo when I’m in. He does a
Engine swap in dump trucks in a day once things are lined up. I didn’t ask price but had the feel it was in that ball park. These guys aren’t putting $30-$40k they don’t have into a 20 year old rig.

Yer right my bad, it was the exhaust.

blownstang01 & Big Katuna,

Thanks for the info. I guess I can stick to my plans and start shopping for that early 2000's Prevost in 5 years or so! I can't afford a new one!!! LOL

B.K., I was thinking the pre-DEF units would be less problematic as well, that's why I was a bit puzzled, but your explanations do make sense.

Thanks again,

An ISX-C Cummins crate motor (if you can get one from Cummins) will run you 40 grand not including install.

In as much as CAT got out of the on road engine business, I have no idea what one would cost but I suspect much more then 40.,

I think that’s it mostly.

Certainly not because they’re problematic. I never implied that. I think the pre DEF engines are less problematic.

Another factor is people with enough money to pay cash buy newer if not new.

Many people would rather pay interest through the nose because they dont actually have much cash and want new.

Another reason as I looked at used is many of them have not been garaged kept and look really used: worn upholstery, carpet, seats.

It’s fairly astounding how cheap the 07 and older DPs are right now. I doubt I can get $30k for my 40,000 mile three slide. And no one wants them. Dealers don’t even take them for trade.

Why is that? Is it because the engines/drivetrains are troublesome? Or is it just the whole pre-DEF thing?

We love our Class A gasser, but my plans are in the next 5-8 years or so, to pick up a high-end mid-2000's DP. If they're problematic, maybe I'll rethink my plans. But if it's something else, I'm thinking I could adjust.

Thanks in advance. 🙂

I'm not who you were asking, but the problem isn't with the coaches. It's that nobody (or Very Few) will finance a MH over 10 years old. If you have the means there are many very good deals on 07's and older.

I was thinking of the other thread that a coach had a bad engine.

A quick Google shows used ISCs for $9K and up.

I didn’t look at remannie but in the engine world they are usually 2-3 times used.

I can’t imagine taking more than 20-30 hours so $2K-$4K labor?

I’m guessing you are attached to your 2000 Newmar. I have a 05 Fleetwood I would like to let loose so have been researching prices.

It’s fairly astounding how cheap the 07 and older DPs are right now. I doubt I can get $30k for my 40,000 mile three slide. And no one wants them. Dealers don’t even take them for trade.

The CAT C7 and Allison 3000 are worth at least half that.

I’ve given thought to selling the drivetrain and sell the coach as a low cost domicile to retired or snowbird located in an RV/trailer Park (lots of them around here) for $5K.
