Very interesting, Late for dinner. I think you just swayed me to the smaller 12' with smaller 4.8 L engine. It's basically the size of a cargo van with more head room in the back, no wider, so I don't see why it would not get very similar MPG as a cargo van.
I'll have to live with the wheel well indents and the gas line indent and a 30" high deck.
If I ever have trouble with the 30" deck, has anyone ever tried a spring job with some monster wheels to bring it up some? It would probably look pretty sporty with monster wheels. Might even improve highway MPG by lowering rpms, who knows.

Here is a dumb comment.
There is a FedEx home delivery spec'ed van I seen a few places and know of one contractor who ordered one to replace his Ford van. I am looking for the spec sheet I had in my library and will post the specs if I can find it. I know the one he ordered is under 10K and meets Fedex 2500Lb requirement.

Greg, the rear axel ratio is, I believe 4.10, but its the only choice from GM. As far as the rear spring "job" I have a set of helpers on my 04 Ford E350 that I got from JC Whitney. They only keep the rear from going down very far, but keep in mind, they dont add to the GVW, but they do add to the empty weight.
The 12 footer I'm looking at has a tare weight of 6500 pounds and a GVW of 10,000. So I should be able to haul 3200 pounds maybe 3100 if I bring more personal items. This get's into the lower C loads.
I'll have to cut a door into the cargo area, and I'll have to find a source to buy the sliding door.

I got some more specs for you guys. The yellow GMC 3500 with a 15' Morgan box has a tare weight of only 6750 pounds. This is only 250 pounds more than the 12 footer and the same GVW. If I remove a couple wheels from the rear axle it should narrow the weight difference to 200 pounds and reduce roll resistance also. I went to look at a 12 footer and because they are more narrow they do not look as good as the full 8' width ones from the rear in my opinion. So they are relatively the same weight loaded and empty. How much could the MPG difference really be, is the question.

i keep reading and re reading this thread. ldb had a legit concern about how the two wheels will help with the load carrying not to mention the onroad flat. i have to add that they are also there for stability when cornering, either in the city or on a country road. they may add rolling resistance towards mpg but thay also add rolling resistance to sliding and sway.
ateam was saying how the twin screws increased ride comfort. maybe you will lose some with the removal of the inner tires. rough ride adds to fatigue.
i don't think all the weight is in the tires. how much more does the box weigh 15 vs 12?
if you do remove those tires you may want to look into air shocks or the air bags that dieseldoctor installed on his srw.

I guess I can keep it in mind as an option whether to remove a few wheels or not. The 12' box compared to the 15' box weighs about 200 pounds less. Pretty darn close, GVW is the same, so I'm just trying to figure out MPG difference between the two. All I can do is guess because there are no specs that I can find on their MPG. My guess is since the tare weight and the GVW is nearly identical that the only difference in MPG will be attributed to the slightly lower aerodynamics of the wider 15' box and the extra rolling resistance of two extra wheels in the back that the 15' has.

For a 1-2% max gain you are making a much larger mistake taking two wheels off. They don't design and build that unit with duals just for grins or just to sell two extra wheels.

You may be right about that, I have no way of knowing the requirements of having 4 wheels back there. All I can go by is the weight which is the same as the 12 footer with two wheels back there.
I went to look at a GMC penske 15/16 footer, the thing is huge. No decision yet.

I went looking at some specs at Motor Trend and noticed a 2002 GMC 2500 can load about 400 more pounds than a 2001 GMC 2500, the 2002 GMC 2500 has a payload capacity of 2947. This gets closer to the 3700 pounds payload of the GMC 3500. Compared to a cube van it is just 300 pounds less payload. Does anyone think this amount of weight will matter much?
The reason I ask is I saw a good deal in my area of a 2002 GMC 2500 Extended. It's a beauty that belonged to a fleet but has near 300,000 miles. I'm guessing it should have another 200,000 miles life in it at least, if it was maintained.

A 2500 is going to be stressed more than a 3500 for the same loads. If I were doing a van it would be no less than a 3500. In all honesty, as much as you've changed vehicle suspects I'd say you should go drive for someone else for a few months and get a really good feel for what you want and don't want and then begin to look for that specific vehicle.
