Moot has a good point on the high side opening being 48". If that's a taper? I'd measure height until I reached the 50" mark (wide) and place that as the cargo width allowance. Love those loads whereby it's 48 inch pallet, but hanging 2" off both sides. Got a quote coming from CA on Monday or Tuesday. Indy was way too high, and that phone call was short.
Hey Kickstart....Just kidding about the hat. Got a couple of weekend loads and missed all the fun.
34,000.00 out the door is a nice price for the ProMaster. Really like the cargo area and the low riding frame for stability. The long version adds 14 inches, but I would not spend the extra 4 grand for it. Would just as soon put that in options, and break the living quarters down on the 3 skid loads. For the money, the 14 inches would improve the living space, but not increase freight, unless you want to run 4x40 at 160". Not me.
Your right about the partition and that being removed would probably make a difference. The feeling cramped part, as stated, probably stems from the Terra Max being so roomy. I'm 6 feet and can stand up easily from the drivers seat. The ProMaster has me bumping my head by comparison. The gas pedal on the Max is placed very deep for good leg stretch, and your sitting about the same as driving a pickup truck. These Sprinter "types" always have me feeling up too high with nothing in front of you but glass. Just kinda weird for me, I guess. Dealer stated the parts department purchased one and is getting a solid 17-18 MPG, which includes running some Carolina mountain terrain...so that lines up, from two sources.
It would seem something like this to me.... If one drives a Sprinter, the ProMaster is similar up front, with the cargo area design being superior
IMV. Given the whopping 6 months in a Sprinter, would have this person grabbing the ProMaster. Time will tell on the motor, but it's the proven 3.6 Pentastar and beats the Max by quite a bit.
As for the OP.....beginning to think the way to go is the high roof already installed and running it like a regular van. They're out there, and found 2 nice ones with limited pursuit. Want the head room and some height for securing freight. However, the ProMaster is impressive and we'll see what quote comes along on Monday. Thanks all, for your input.
