Is it a SRW or a DRW truck? That TC is way too much for a SRW I believe. I would weigh the truck and then see what you have.
One thing you have to remember is these new SRW Chevy and Ford trucks can have a GVWR of over 11,000# not like your Dodge with a 9,900 GVWR the same as my 2006 3500 Dodge had with a diesel. My 6.2 truck has a GVWR of 11,200#. This is 1300# more than my Dodge and my 6.2 engine is sure lighter than my Cummins was.
The heaviest NL is the 10-2 CDSE and the dry weight on it is 2970 and this is with almost every option the NL offeres but it is standard on the CD unit. About the only additional is the generator. NL weighs every unit when it leave their lot and puts this weight in the cupboard. I use to own a 10-2 CD and know that I didn't overload my 2002 Chevy EC 4X4 Dmax/Allison and it had a 11,400# GVWR. This unit is less than 300# more than your unit but it already has the AC on it with side, rear awnings, electric jacks, dual pane windows,TV and DVD, microwave oven.
He may have to go with 19.5 as you did on yours.
This is IMO
I spoke with the sales rep. up in Portland OR, my closest dealer. He ditto's what you said about the weight being inclusive with the options. I figured with an additional generator, solar panel, full water and propane tanks and 500lbs of gear (the gear migh be high), I will be at 4,000 lbs. I think cargo carry capacity of the truck I am getting is 4,192 lbs.
Once upon a time, I had a 2011 Chev 2500HD ExtCab 4X4 6.0 and 4.1 gears. Taking it easy, I got max of 8MPG towing my 9K TT with 1000 lbs tongue weight. Went all the way to 12 empty once again taking it easy. Had enough power, but coughed going by gas stations. Went back to a diesel, same year, Crew Cab 4X4 6.6 Duramax. I get right at 11 towing same TT and close to 17 empty. Just my experience, but you do what you want as it's your money. JMHO
i have the same truck only in 2500 dress.unless you enjoy a transmission that will downshift on the tiniest grade DO NOT repeat DO NOT even consider anything less than the 4.10.my 2011 6.0 with the 3.73 rears gets between 9 and 10 mpg with the TC (8.5 North*)which is much lighter than a NL.if $$$ and reliability were not a consideration i would have went the diesel route.
I would go with the 4.10 for sure! I wish I would have when I bought my 2005 Ram 2500, it was a big mistake not getting the 4.10. You will get much better performance out of the V-8 if you can keep the RPM's up while working it, that is how V-8's are meant to work, at higher RPM's.
If and when you do get the truck, post the performance with the camper on it, especially if you decide to go with the 4.10. I am interested in the exact same setup.
So is the consensus that a 6.0 gas engine and 4.1 gears has enough torque for the planned load and boat?
(I understand the cost and weight penalties of a diesel, but axle gearing wouldn't be my first worry in that situation)
