98 B3500 Van Conversion: 4.10 to 3.55 swap?
Edge products evoht p/n 36030 appears to support 98-2003 vans.
BUT they also have a disclaimer that they do not support cab and chassis vehicles which is what all conversions vans are.
Could be worth a call to their CS line. Since C&C's are 99% same as work vans except for a few extra electrical circuits.
I would think that going to a single rear wheel set would save on fuel. When the price of gas first went high many people went to super-single rear wheel and tires. Back then, Dick Cepek sold lots of 12-16.5 conversion kits for fuel savings.
Our conversion van is a A1500 Star Craft conversion. On certified scales it weighs 5900# with tractor tools and stuff.
It has the V360 and 4 speed OD 3.55 gears with P23575R15 27" tires!
Around town on short trips it gets 10 MPG
On the freeway with cruise set to 65 it gets 15.9 MPG.
Towing a 7000# load [I use it as a tow vehicle to relocate a utility tractor that weighs 5000# plus the trailer] it gets 9 mpg, overdrive locked out taking it at 55 MPH flat terrain. Towing the trailer with out the tractor 13 MPG (pulls so well you will forget that the trailer is attached)
I gets better MPG than an F350 V460 C6 ford did on same load (3.55 gears)
Fine tow vehicle, front and rear AC and heat that cools even in 110F Texas summers.
I do not expect it to stay together long working hard but the price was right.
A true mileage test is over the hill to El Centro and back to SD!

My motorhome started life as a B3500 van, and was split down each side from the front wheelwells all the way back, adding a wedge that measures 0 at the front and 4 inches at the back. Then, they added a one-piece fiberglass cap and tail to it.
I gotta get my rig weighed. I would be very happy with 15 mpg. On a 2 hour trip last Saturday, I got 13.7 mpg.
Thanks!

Torino,
Give a call to Oceanside driveline for another option.
http://www.oceansidedriveline.com/
Not sure how the compare to others around town, just know they came highly recommended by everyone around here.
They had no issues putting my raised roof on a lift when they put new bearings in a junkyard axle for me.
They scrubbed and painted the axle for me too. Still looks good 6 years later.

Thanks for the recommendation! I emailed them my info. One of their units has a video-in port for a backup camera! Interesting!

Does ANYONE support the 98 B3500 van?

On Saturday I was speaking to a gentleman from the Midwest, who installed a Cummins 6BT in his extended Ram Wagon, the only one I know exists He also uses a Gear Vender overdrive unit which allows him to run 3.92s and lower his RPMs on the highway. Likely a better choice for you than installing 3.55s in your MH which is probably near its max GVWR unloaded.
Here is a person who just squeezed the 4BT into a RAM ....

There are ways to improve the mpg. One was mentioned with the LT load-E tires. Even Chrysler has a TSB for doing this.
Also, to help with the MPG, change out the rear oil from 80w90 to synthetic 75w90 with the friction modifier. Redline sells the product and Chrysler approved it's use for the Ram Vans from 1994-2003. I had dug around for that TSB under the fleet use section.

Also, some of the Jeeps used the Magnum engines in the same era as our vans. Here a person swapped out a 5.9L for the 4BT Cummins diesel.
