I am looking at a motorhome that is built on a 1988 Ford E350 chassis. We
are considering a 27ft Class C model that is built on an Econoline Van
chassis. The motor is the 460 with EFI. I assume this is a multiport as
opposed to throttle body injection. Is my assumption correct? I also
understand that the C6, 3spd tranny is better (stronger) than the OD model.
The 3spd has a trade off in mileage, but it picks up a little in the
reliability department. Is this true?

I will be flat towing a Jeep for a while, then switching to a trailer to
avoid driveline wear & tear on the Jeep. I also am making an assumption that
the GVWR will not be exceeded when I put my Jeep on a trailer. Actually, I
am not sure which spec I should be looking at to support a trailer and Jeep.
Maybe one of you guys could run down the list of GVWR (gross vehicle weight
rating), GVAR (gross vehicle axle rating), etc. I am not sure what the
ratings are, and which ones apply to motorhomes dragging Jeeps (I am sure
that the ratings don't really care that the load is a Jeep, boat, or Mother
in Law), or which ones need to be combined.

So, my questions are,
Is the '88 Fuel Injected 460 a multiport design or a throttle body design?

Is the 3spd C6 tranny worth the added cost of extra gas, or is it a myth
that the OD tranny doesn't hold up well to pulling the weight of a motorhome
and a Jeep?

What are the various weight ratings?

TIA,
Jeff

The RV weighs 11,200#. The CGVR (Combined Gross Vehicle Weight) is
18500# which is less than the 15200# for both.

Just for clarification, that *should* read "The RV weighs 11,200#. The CGVR
(Combined Gross Vehicle Weight) is
18500# which is MORE than the 15200# for both." (The CGVR is higher than the
weight of the home plus the Jeep.)

This is good news because the CGVR gives a margin (in your case, and I
assume mine) of 3300#. I can not see any trailer weighing that much, which
would still leave a comfortable margin. I am a little bummed that the fuel
injection is a throttle body instead of a multi port design. I am a cheap
SOB, so I guess that I can't really complain. I wonder if there is such a
thing as a MPFI kit for that motor that makes the Smog Cops in Calif.
happy.....

Thanks,

addressing the E4OD transmission problems in ANYTHING built on the E350
platform..........most had improperly calibrated dipstick/tube assemblies,
resulting a 2-3 quart underfill.

Which is disastrous.

If you have an early E350, before about 95, pull the pan, check that the
'full' mark lines up with the pan mounting surface.

Then use a 4WD pan (deeper), fill to the mark, then overfill it a quart.
Because it takes a quart and a half to fill all the clutch packs in OD.

Of course, LARGE external coolers are a must, and bypass the cooler in the
radiator.

I am confused. I have found a truck that does not have an OD transmission.

I *think* that I will not need to make the check that you describe since you
seem to be talking about the OD model. I don't mean to be argumentative,
because I don't even own one of these yet, I just am looking for information
before I make a purchase.

I have a 1990 E350. It only has a 351, to pull the 21 footer.

You mention "Vapor lock". I offer, any time you are heading down the
highway and the engine sputters to a stop. Then after 15-20 minutes,
it fires back up and you are on your way. The problem is the fuel pump
in the gas tank. It heat up and jams. After cooling down it's on
again. Been there, done that.

Bill,
If I did not let the engine temperature rise, then I had no problem. The
first time it sputtered to a stop was when the engine temperature was a
little above the half temp mark on the guage. The next time was about 20
miles later at 55mph. The next 200 miles I watched the temperature closely
and didn't have another occurrence. I was also thinking electronics in the
engine compartment that were sensitive. It was a HOT day , 95-100.

From what I read, the the tank has to be removed to get the pump out. I am
saving this as a last resort, but maybe I have to bite the bullet and do it.

Jeff,

The high temperature is probably what heated up the pump in the tank.
It is a $300-400 job.

I just remembered another question, What are the likely axle ratios that I
will find?

I assume that the chassis' on these trucks are in stock trim, but I don't
have any way of knowing for sure. I would guess that they are setup with
4.10s.

That motorhome will be so heavy, you won't be able to keep it in OD on a
hilly interstate, even with the 460 and 4.56 gears. So it probably
wouldn't do you any good. I think it would be okay someplace flat,
though.
