Can't complain about the performance of our 8.1. It has plenty of power and I consider our coach one of the heaviest gas coaches ever made. We tow a PT and avg 7.5 to 8mpg at 62-65 mph. Do check out any W20-22 Workhorse chassis maintenance records and be sure that the brake recall has been performed. Good Luck.

thanks in advance.

I will second this, 8.1 is a good engine, I live atop one myself, in seven years other than oil changes and filter changes the only things that have been done to it are....

Repair rodent damage to wire

Replace serp belt.

(That was fun, I spent about an hour on my back under the rig with pliars and tin shears cutting half the belt off what it wrepped around, (The other half was still there) drove to Seneca SC with the half remaining, went to a pro to have it replaced, they did a Domino's job (30 minutes or less).

I'm happy with mine, if I was looking into a gasser I would do it again.

We've only had ours a few months now,
but just completed a 8730 mile excursion with 0
problems. Clock now has 54000 and change.
Po did headers, does use a little oil, did a decent enough job in the Rockies.
Would have liked a bit more power going up.
Avg 8 - 8.5 mpg @ 63 -65 mph.
So far very happy w/ 8.1, Workhorse and Newmar.

You have a GM 4 speed transmission. Its a good tranny but 5 gears would be better.

We've got a 2005 Dolphin with the 8.1 and Allison 1000 series tranny on a W22 chassis. Had it for 2 years and so far no issues, aside from a spark plug wire working loose and causing check engine light to come on. That by the way was an easy roadside fix with a gloved hand. We averaged 7.5 mpg on a 2500 mile trip last summer from Reno, NV to Sturgis SD, that included a lot of steep grades.

I too own an 8.1. W24 Outlaw. Only thing I did was put Banks headers on it and ultrapower chip. Headers took most of the heat away and put the POWER to the PEDDLE. Love it. Tony

B-in-Law , had one;Tiffin 35' 8.1 Allison, W-22 chassis; for 2 years and was happy with the performance.
BUT... the low CCC of 1300lbs always had him running at the GVW of the chassis or over. More to look at in any MH than just what engine/ trans, combination it has. A 35ft coach has a lot of storage space, but a low CCC ( Cargo Carrying Capacity weight in pounds ) can be even more important.
JMHO. in a 35' coach look for a CCC of at least 2,000 lbs or higher.

I own a 2005 Allegro Bay with an 8.1. It was purchased new in 2005. I knew an owner who had a fire in the rear of the engine (which was covered by warranty at the time) I installed a small blower (boat bilge blower) at the front of the engine compartment and ran aluminum ducting back to the doghouse opening. I have had no problems to date. The install cost me about $90. My friend, after the engine fire had Workhorse install theirs which cost him $2500. Theirs had no power fan, just scoops and ducting.

our deal on the 35' with the 8.1 vortec fell through , the day I was supposed to call the owner back we found out that our nephew had passed away , so it was a couple days before I thought about MH'S. , but we are still looking.

Sorry to hear that.. Seems the older we get the more funerals we need to go to.. Alas, that's not so bad, the only funeral I really wish to avoid is the LAST one I'll ever go to.
