For the record, there is inadequate room under the rig behind the rear axle. I think it allowed the RV manufacture more flexibility in floorplan design of their various models without giving up the spare.

Ron,

I wonder what's driving the difference in our two base motorhome designs ...?

I believe yours is approximately a 24 foot rig on the E350 and ours is approximately a 24 foot rig on the E450. Our wheel base is 158 inches ... what is your wheelbase?

Since ours is a basement design (~7 inches height difference in the cab and coach floors), our 29 gallon grey tank can actually fit up between the spare (which is mounted between the longitudinal frame members) and the coach floor. I wonder if this is causing the difference in our spare locations?

We measure 23'-8" long and like you, we have the 158" wheel base, but we have only 2" height difference between floors. That must be making the difference. Our rig has a lower profile than most with the over-all height at 9'-10" to the top of the a/c unit.

How tall is your rig to the top of the a/c unit?
