more power

Econoline does not get the three valve V-10.

That's right :S didn't dawn on me this was a stripped commercial econoline chassis. Now the question is did Ford put the redesigned 3 valve exhaust manifolds and Y pipe on the 2 valve at some point. If not then exhaust help is very much needed and custom tunes.

With a gas engine pulling 20,000 lbs, unless your on flat level ground without head wind, there is no reason for overdrive.

It will pull great in overdrive (even at 25,000 combined) if the breathing is improved. Since mine now makes much more low end torque, I've changed to programming accordingly to hold OD to a lower speed and under more throttle, which keeps in in OD about 99% of the time.

I started looking at all of the power improvements when I first got my Winnebago (also 32' on the E450 with the V10). If this is your first year with the RV you may want to give it a little time. I ended up doing nothing for extra power. Towing a Jetta TDI I found it didn't justify the cost of the modifications for the minimal change in power I'd end up with.

I think it's been said already, but unfortunately, with any gas motor, the best upgrade you can do is exhaust(get that cat out of there, and a free flowing muffler), and a tune. Even with that, you will net ~50hp or less.

If it was a diesel....much different story... Very easy to get an extra 100hp just from a chip. :)
