And I still don't see a psd in it either.....hmmmm.

 

So we are all in agreement then, PSD are the best!

 

That's what I'm hearing.

 

In your story you were referring to a SD with a box on it. The 350 thru 550 chassis cabs are also available with the V10 and can accept a large box as well. The GVWR of the V10 equipped truck should be slightly higher than the PSD equipped truck also. I take it you never saw one of those E-450 shuttle buses with the very large windowed fiberglass/aluminum (or whatever) passenger box. Then those buses get filled with people. Then there is the F53 chassis that has been mentioned before. You limited one sided experiences do not create fact nor produce accurate factual assumptions.

 

And they'd probably be a complete bitch to heat in the winter. Or cool in the summer. Steel conducts heat (in BOTH directions) very well

It's called grasping at straws. Box trucks are all made with aluminum, whether they be diesel or gas. Why? WEIGHT. The GVWR is a set limit, and the heavier the box, the less you can haul.

But don't let logic get in the way

Been looking at the local utility trucks around here, Verizon is running 2008-2010 F450/550 chassis-cab bucket-trucks. Powered by what? V10s.

Same for the Long Island Rail Road, Long Island Power Authority and a few others. Just about one in 5 is a PSD.

 

Our CA government was using natural gas, propane and fuel cells in their fleets. They have programs that will go regardless the cost, so you can't seek logic in it.
In the mean time I keep paying attention to those car haulers using 1ton pickups for 40,000lb sets. I don't take notes, but roughly Fords make 30% of that fleet. 70 are Dodge. Have not seen a single Chevy in this configuration.
You are mistaken Krewat about the body insulation. Frame makes little heat transfer. It is the actual insulation that does make whole difference. My bus is having polyurethane insulation, what beats fiberglass by multifold. Bottom line the 40' conversion will get warm with 1500 W heater, while same heater would not keep warm 20' wood/fiberglass motorhome I used to own in the past.

 

what % of the fleet is v10's ?

 

It is not easy to read the side emblems on the freeway, but so far I noticed ZERO

 

Insulation aside, RV's still have to deal with a GVWR. The heavier the body, the less they can haul in terms of water and cargo. It's not about diesel vs. gas.

F53 chassis of either gas or diesel are the same GVWR, everything else being the same.

 

That is the whole point of using gasoline engine on those chasisis for RV conversion (beside the price).
Almost all low and mid priced RV have their suspension capacity used up to maximum. Lot of motorhomes build on F53 have cargo capacity of 300-500 lb.
You put heavier diesel engine, you will loose 300 lb cargo capacity. Do the math?

 

Actually, the point of using gas for some people is they don't want the stink of diesel with an RV. On top of that, they can sit for months at a time, and a diesel won't hold up to that type of "abuse".

 

Wrong again
Almost 100% of motorhomes that sell above $100,000 are diesels.
Unlike gasoline, diesel can sit in the tanks for several years with no ill effects. Diesel injectors opening at higher pressure will not let the fuel to gunk the engine as well.

 

its because none of those organizations give 2 cents (in place of another 4 letter word with s at the end) about fuel cost. neither would i if i wasnt paying for it. . .verizon customers fill the utility vehicles, and tax payers pay to fill the others (and since when has any form of gov't been responsible for their funds, or been infamous for rational decisions? i think your bankrupt state could benefit from usin fuel efficient vehicles. . . .as could the rest of the country). all the above said organizations have a long history with ford, and have ongoing contracts that are proposed before trucks are even designed. . .so they dont even know exactly what theyre in for. i could cite a different example, showin more of he guys who haul big loads everyday, FOR THEMSELVES, opt for diesel. prob 5 diesels for every gasser. . .like i said before, ford guys need the 6.8 so they have an alternative to the infamously poor reliability of the last couple motors. dodge ditched their v10 not only cuz it was junk, but no1 bought them because their cummins powered counterparts (p-pump'd 12v's) were the most reliable things ever put into a truck.

all that bein said, if i HAD to choose between a 6.0 and a 6.8, i would pick a 6.8. if i HAD TO KEEP emissions on my truck (i.e. the new common rails), and my only other choice was a 6.8, i'd get a 6.8. but lucky for me, there are plenty of better choices than all the above.

someone said maintenance of a PSD is 3-5x the cost of a v10? ? ? would ya like to explain to me how that math works out? ? ? if anything, the maintenance costs break even, and doesnt include the cost of overhauling the v10. . . .which would inevitably occur much more frequently than a diesel.

 

Those that can afford a diesel RV buy diesel pushers. I believe they start at around $100,000 and above. They are in the back so the driver and passengers don't have to listen to it while driving. They are a big box, so they are under a load even on flat ground. The old ones have the V-6 or V-8, 2-cycle Detroits in them. The newer ones have in-line 6 cylinder diesels, cummins or detroit. I have never seen a cat in one, or an international either.

 

Motorhomes using Gillig chassis are powered by CAT engines.
Funny part you can see lot of Barth trolleys all over the country. They have the same chassis. POWERED BY DIESELS
