Find out what the GVWR of the RV is then take 25% that is what you should figure as your pin weight. Load your truck with bodies, fuel, hitch gear and hit the scales. Take your RAWR and subtract your actual rear axle weight. If the 25% number is less you are fine.
Personally I would not tow anything that long with a SRW.
YOU DO THE MATH.

There should be some common sense used with these ratings.
Example my truck and trailer combined max rating is only around 18K with 3:42 gears. The exact same truck with 4:10's is rated combined at 30K. In my opinion all I am doing is possibly wearing out the drivetrain. My combo weighs 28K.
To be any use at all, standards have to be objective. Keep in mind that the standards have a number of criteria; the GCWR (and thus tow rating) is based on the lowest weight at which a particular truck will pass all the criteria.
So your truck with the 3.42 might meet all the criteria at a certain weight except for one; it fails at that weight. And close doesn't count. If the criteria is "Maintain 40mph up an 11 mile 7% grade" and the truck can only maintain 39mph, it hasn't passed.
Like I said I may damage the drivetrain (don't think so). But it is just as capable of getting the load down the road safely as the one with 4:10's.
My 15 RAM will have factory rear air ride and 4:10's.

I have the 2013 Ram 2500 Laramie Longhorn Crew Cab 4X4. It is rated @ 370 ponies @ 2800 RPM, and has 800 ft-lbs @ 1600 RPM. There is no doubt about the juice to pull. Rated for 17000 and change to pull. As for stopping, it has factory electric brake control with auto sensing adjustments as well as factory J Brake with auto sensing or manual if wanted. Also has hill assist. HD alternator and transmission cooler. This model also has auto air intake that decides if it wants to take air from the cab or the outside depending on temperature/humidity etc...
As for the weights, I am fortunate to work where there is a scale, and weighed in today. 4940lbs on front axles and 2960 on rear with me and a cup of water and a smile from ear to ear. I got a hot little wife and a 3 and 6 year old whose combined weight might equal that of my 225lbs. Throw in a bit of "junk" for the road (200lbs at most as anything else would be in trailer), and if that was split between the front and rear axles evenly then you could say that I got 8600lbs total for truck. So far, that is 700 or so payload from the 2600 the truck is rated for. That leaves me 1900.
Trailer I am looking at is a copper canyon 324fwbhs (2014), and it has a dry weight of 10800lbs and tongue of 2100lbs @ 20%. Yes, that is a little over the payload for the truck that is left, but if I load properly that can be compensated a little, and if not, then well If that truck can't handle 200lbs over then I should have left it there at the dealer (and helped you Ford and Chev guys with pushing your trucks home.. LOL). I know from my work that there are "error" factors built into these ratings so that there is some room for people (like me) who push the limit. Usually it is anywhere from 25 to 50%. Rarely less than 25%. In other words, the real designed payload for 2600 rated would be 3250 to 3900lb.s, but the lower number is the "safety net" to protect the engineers, Ram, etc...from liability for people who push the limit. After all, if they said it was good for 3900lbs because that what tests showed to be the limit, then people would be all over them like gravy for the anomalies that snapped just below the test limits.
What I am really interested in is hearing from people with similar vehicles and set ups and hear how they have fared in regards to tranny's, control, heating etc...
Again thank to all those who are trying to help - and thanks to the condescending bunch as well as you keep a smile on my face and entertain me.
