Ford v Chevy

We are looking to upgrade our MH and we are wondering about the engines. I know some folks like a brand because they like a brand. I'm not partial to a brand but I hate to make a known bad choice. We are looking at a gasser but there seems to be three choices, the Chevy and Ford 460 and a 6.8. Any specific known problems anyone can share ? I know asking about mileage is a sin but we're just looking for some generic info. We will be looking in the 30 - 35' range so if that helps we'd appreciate any input. When on the road we do 58 - 62 MPH's.

Thanks

I can only speak to the 6.8L's.
They're solid motors, built for a long time. Still in production.
Some vintages have one of two problems:
1) Inadequate threads on the heads to hold the spark plugs. This isn't a problem as long as the spark plugs are *carefully* changed and properly torqued. If over torqued, under torqued, or cross - threaded, they can blow plugs out the top.
2) Some years had an issue with plugs coming apart in the head upon removal. Again, there is a process to keep this from happening and a special tool to address it if it does.



The 6.8L will have better diagnostics than the 460. I don't know anything about they Chevy.

if you have the money i would go with the UFO its a gas pusher

its GM and has the allison and i think what you pick is more going to be off the trans


i made parade floats for a living so my job was to cut up trucks and edit them .. mostly the same thing that they do with Rvs .. and in my post ford has never been good with edits or pushing some thing for more then it was made for .. like in a RV

so for that alone i never became a ford guy

but if you are going used it is sad but you well more wind up with a ford as there are more of them out there

All depends what year you are looking for. Up until the late 90's you had the 454 chevy and 460 ford, both V-8s. Ford then switched to the V-10. Workhorse bought the Chevy MH chassis business. They implemented the 8.1 L V-8 coupled to the Allison Transmission. More recently ford has added an improved automatic transmission behind the V-10. Chevy quit making the 8.1 L as a result of the economic downturn. Workhorse was forced out of production. Gas chassis increased in capacity to Workhorse 25,500lbs. and ford 26,000lbs. For the last few years, ford is the only gasser choice available in the American MH market.

Note...... early Workhorse units had an important brake caliper recall and issues with the auto park brake (both can be corrected). I enjoy fulltiming on a Workhorse chassis.

Mine had the chevy 454. Got a good set of thermal boot plug wires and it was one of the only parts of the RV that ran reliably,especially to florida and back (94 TBI). Got maybe 7 mpg tops. Was told by one RV mechanic to run away from anything with the ford 460 in it, but there are tons of folks that swear by them. Think both units are under powered for a class A, so would look at one of the new 3 valve/cylinder V10 IF my dream of a diesel pusher can't be had. Good luck.

We bought an 01 Adventurer 35' with the Ford V-10 with 12K mi. We drove it 7.5 years up to 81K mi. and NEVER had an engine or tranny issue. I did have the tranny flushed every 20K, however. That engine is solid and can run 4K RPM in second gear up a hill easily. If I was going to go back to gas, that is what I would get. JMHO.

Pleased with Ford V-10

First RV was 25' Class A with Chevy 454...kinda underpowered.
Second RV is 32' Class A with Ford V-10...lots more power, good transmission...highly recommend...if you have to worry about gas mileage, don't buy an RV!!

Keep in mind GM has not made a vehicle in the past 20 years that hasn't been recalled

GM hasn't made a motorhome chassis since 1999 ..... 15 years ago. GM hasn't made a motorhome since 1978 ........ 36 years ago.

We have a 1998 Windsport with the ford 460. Even with its age, it gets 8.5 mpg. No problems with engine and tranny.

In either case, later years would be better. I like the GM for two reasons. First and foremost is the Allison Transmission. Second, the larger displacement provides plenty of torque and 2,400 RPM seems to be a sweet spot. At that RPM, the noise is relatively quiet. Not having the Ford I can't attest to this, but from what I understand they tend to rev the Ford's higher to develop the torque and therefore there is a bit more noise.

I don't know where the sweet spot for torque is, but we are just a hair over2000 rpm at highway speed.
