My extensive HIGH ROOF van surveys (no disrespect to anyone.) I have over 5 year in automotive industrial engineering consulting for all Tiers of automotive manufacturing for all the main manufacturers in USA (although almost all of them were from abroad: Fiat, Bosch, ...)
1. FORD Transits -
good - Ford GT (race car) power plant 6 cyl,
- lots of repair dealers (and you'll need them, because it will be a part time job as long as you own it!)
bad - light weight frame (uni-minded Ford engineers/reps/employees- whatever the boss says and nothing else) bends almost every time you go over a speed bump,
- Constant alignments and frame bends and tires - $$$$
- too many loose ends of design that are never fixed (see US main Transit forum),
- it takes years to find out all the options available because you have to go to a 2 year school to figure it out - WAY too many unengineered options - $$$,$$$
- anything but the GT power plants are sub standard, and dealers just keep rotating the other ones to vacant parking lots continuously(!),
- Ford Transit's main color (WHITE) is a PRIMER paint which is a cost saver carried over from Europe where it was introduced. You need to really get a White color dual painted!
- No HD V8 engine for a HD van (it's not a race car)
- Up to huge cumbersome GoodYear blimps of soft AL that make driving a tractor trailer look easy.
2. RAM Promaster -
good - unlike Ford Transit's odd shaped cargo area, it is a conventional cargo area refined in Europe for many years as I understand it.
- like Ford, it has a Maserati 6 cylinder race engine.
bad - under-duty minivan transmission $$$$$.
3. Chev/GM (I did not originally include it in my High Roof Van survey because they did not make one, however I'll give some of my automotive engineering background experience: which MAY NOT exactly correlate from automotive to trucks!)
good - stable unchanged manufacturing design for decades
- v8 engine
- good transmission
- good ac
- heavy duty steel frame
- anything Bob says additionally - I have since learned a lot of good GM features from Bob that make logical sense
bad - they don't make a high roof,
- GM is the only company that makes an 15% excess for engine rebuild parts (and they use them)
- GM's are the best manufacturable parts due to a wide manufacturing tolerances - thus engine rebuilds, and excess oil usage - sometimes driving off the car lot,
- I used to think GM's had the best paint jobs, but a GM enthusiast and paint/body shop owner told me they look good because they get repainted soon after they drive off the lot (but I hear they are good-to-go after a fresh rebuild and paint job.)
4. Nissan NV 3500 Cargo Van
good - biggest most powerful hd v8 engine in van class
- faultless defect record
- little risk in used vans
- cheapest of all new high roof vans
- best handling van due to longer pickup truck front end
- best ergonomics (stretch out) due to longer pickup truck front end
- best Japanese electronics of all High Roof vans
- long successful (identical) product line from 2012 to 2016
- best 5 year 100,000 mile warrranty
- Cheapest new van possible
- heavy duty steel frame
- 6' - 5" cargo headroom
- only a FEW well engineered options for a superior designed vehicle
- Japanese quality (My first one
- 3900 lb payload
- almost 10,000 lb tow with class 4 hitch
- several 12v and several 110v outlets in front and back, from new
bad - due to pickup truck front end for a 20' long vehicle, cargo space is limited a few feet of space,
(Buddah says greed does not have limits, and it makes you engineer your space from what is available)
- All Nissan High Roof vans are 6k lbs heavy, but for a hd van, it's more of a benefit than the couple of mpg's lost, imo.
- the Ford Transit forum guys say it's ugly, as they drive off sitting on a pickle barrel
- mpg - > best - 15 to 17, avg city traffic - 12 to 15, drifting or hauling A - worse (but it CAN haul A, although I'm cheap and don't do it.)
---------------------------------------------------------------
That was approximately how I paretoed my buying factors: high roof, heavy duty, well engineered, Jap electronics, best handling, alignments, transmission, ac, maintenance warranty/reliability.
Things I let slide are 3 mpg and carrying a 10' x 10' storage with me (but it is 6'-5" cargo headroom!) Soft AL frames/alignments/bent frames and minivan transmissions are much worse and much more costly factors that effect a HD van owner! Ymmv!
