the Ram site is kind of hard to go by,  i would look at the label on some trucks that you see on the lot because the payload changes quite often depending on options and trim packages

Thank you everybody for your comments.  Seems the diesel might be/is an overkill as the 3500 would be as well for my set up. But, I perk up when I read MPG in the upper teens while hauling a camper. Not all diesel owners are as fortunate, actually. Then I read high maintenance cost, road side break downs, California's extremely high registration fees and taxes, blah-blah-blah, sooooo discouraging.  I should also say my annual mileage is about 15,000 mi/yr. I like the idea of more than enough payload too. Perhaps the 6.4 w/~3000 lbs payload is closer to a reasonable choice, then there's the low teens MPG, sigh!!!  What (still) to do?

According to the Ram site, the payload for a 2500 crewcab is 2230 lbs - that was the only reason I tossed around the 3500.  Sounds like the 2500 handles the camper just fine though and would suit my needs

2500 crew cab with a cargo capacity of 2230lbs is for the 5.7L hemi, which has a gvwr of 9000lbs. the 6.4L hemi option raises the GVWR to 10000lbs and 3100ish cargo capacity. my laramie, as outfited (things i didnt even know i needed) door sticker has cargo capacity at 3080lb.

 

as for gas milage, my 02 tundra with FWC hawk installed got 7-13mpg, average was 9-10mpg. seemed lole 9 no matter what i did. im getting consitant 13.9mpg with the 6.4L hemi 2500 which only has 800 miles on it (ie, not broken in yet), not 100% awesome, but ill take it

coguzzi...thanks for your info..  I read on the Ram website spec sheet that the payload for the 2500, 4x4 "diesel" Crew Cab- short box was rated at ~2300#.  Same truck set up, but with the 6.4L engine was rated ~3000#

i realized that as i was sitting drinking a beer, diesel is 500 lb heavier motor--so yeah--2500lb-ish. doh. i should always have a beer BEFORE i post--ha

I hear you on the mpg. Low teens vs high teens is a huge psychological barrier for me. I swear that if my Nissan Titan gave me just 2 extra mpg, I would take her out many thousands more miles a year than I do right now when i get only 13mpg. 

But then what i cheer myself up knowing that when I bought a very capable truck used for 1/2 the price of a new one, i saved $20k right there. Still, i agonize about getting 2mpg less than what i expected/hoped for. Such is life. the grass is always greener etc...

I don't really think the maint. cost is that much.  It might seem like it but the biggest cost is oil changes.  Only synthetic BUT generally only every 10k miles.  On my gas engines, 5K miles.  If I could afford it, I'd get the diesel engine on a truck.  I have a diesel VW but my truck is a gasser.  Don't forget about longevity in your cost/benefit analysis too.

Mike....High vehicle registration and taxing fees on a 3500 every year does not excite me.  Cost seems high!  A 2500 gives me the payload for my loaded Hawk with padding to grow.  Perhaps DMV fees in CA are high on the 2500 too?

Good to know, I didn't think that 2200 seemed right. This is making my truck choice hard on me!
