I agree with Grey--even the best gas motors are ready to be rebuilt after 201k--and god knows how much idling. And rust inside = wheel arch issues. Fixable but a pain.
Too small will be regetable for a long time-and unless you want a project-and can work it into its final cost-keep looking for a 16 passenger-its a common size.
WHOA! The differences between E350 and E450 are HUGE! Offhand...
MUCH higher GVWR (14,050 versus 10,700)
Higher rear axle rating (9450lbs versus 7600lbs)
Higher front axle rating (4600 versus 4200)
Hydroboost brakes (even on gassers) with 4-wheel discs (A 1998 E350 will have rear drums.)
Larger engine (the V10 was standard, E350's have 5.4's standard)
Larger rear axle
Larger fuel tank
Larger trans cooler
Standard PS cooler
A diesel E-350, even a shorty, is pretty much guaranteed
to be overweight when converted! It is probably right on the edge of the front GAWR just as it sits now.
What year is the E-450? If it's a 1997 or newer, it's a Triton V10, one of the best truck engines ever built...truly, 200K on a V10 is no big deal, it could easily wind up twice that (or more). The body will fall apart around it while the engine keeps going. I saw one (1998 E-Super Duty, Champion WC body) with 180,000 hard miles, about 16,000 hours on the engine. It ran perfectly, the company still has (and uses) the bus six years later. I'm certain it's over 200K, it's probably near or over 250K.
I also saw one wind up 430,000 miles (it's still running) in one of the harshest applications imagineable: it powers a 2000 F-550 4x4 with an Eagle Claw self-loading hoist...a repo truck.
