Hmm. 1984 F250 HD original owner here, 460 ci V8, manual, 4wd. Too old for comparison. With 140k, RR'd clutch 2x, xnfr case 1x. Leaky rear engine main due to crankshaft machining defect from factory. Not coolio.
Had a 96 Dodge 3/4 ton diesel. Great pulling / towing machine. Lousy for a full size heavy ass camper. 12 valve motor. Sold because of 'wallowing wallida' syndrome.
Current ride is 2002 Dodge 1 ton dually. Handles the camper wonderful. Original tranny RR'd at 120k miles. Everything else (engine, xnfr case, diff's) still going strong. Interior looks good great too. 'Zilla don't know **** about Dodges.
She is a bit slow on the up hills under load - and noisy. Then again, even a cretin can fix it.
The newer diesels are quiet, look coolio, and cost like what, 50k?
Me, I like the no monthly stroke. 500 clams or more per month sucks.
Buy/lease gas. You guys don't put all that many miles on per year to justify the diesel. INMHO, of course!
