Gas vs Diesel

QUESTION:

I need to pull a mini excavator. It and the trailer will weigh almost 10,000 lbs. My '91 F250 diesel that I bought about a year ago, has a cracked head - $3,000+ to fix. I may trade it in and get another, perhaps a Chevy.

I'm wondering if a larger gas engine might be a better route to go? Any opinions?

ANSWER:

make that Ford buys a pretty good diesel... same with dodge... gm is the only one that actually produces their diesel engine (through a subsidiary). the excavating contractor my former employer used to use had a finish grading crew that towed a 8,000+lbs tracked takeuchi skid steer every day behind a '98 C3500 with a Vortec 350 in it... the guy that drove the truck said it had enough pwer, but he wasn't racing it either. this was in Maine.. fairly hilly counrty too.

I pull a Bobcat skidsteer pretty regularly with a '99 C2500 350 auto. No more than enough power and the auto wants to shift a lot on hills. If it were mine, I'd go for a C3500 and standard trans. 350cid would probably be ok with this setup. Diesel would be better, just depends how much money you have to spend. I've also used a Dodge 1 ton with V10, 5 speed which pulls it nicely. Both trucks get real thirsty when pulling the Bobcat.

Get the Duramax with the Allison tranny, you'll be glad you did. Ford makes a really tuff truck, but their diesel engine that they use (Navistar, read International Harvester) is quite over rated. A diesel should get half again, maybe close to twice the fuel mileage over a gasser when towing 10k, if that's a factor. Diesel fuel simply has more energy per gallon than gasoline. Been there, done all that.
