If you feel you are "unsafe" with that combination, you need to be talking to your dealer BEFORE you accept delivery. You may be able to switch to a lighter "more tow-able" camper before the contract is "finished" when you sign at delivery.

If they will not "re-look" the deal, walking away from your earnest money may be your only option. Not what you want to hear, I know. Salesmen are selling on commission and DO NOT have your interest at heart AT ALL.

The camper dude wants to sell you the biggest most expensive camper her can talk you into and the truck dealer wants to move that shiny "Cowboy Truck" with the bucket seats; 4x4; and over-sized mag wheels that has been sitting on his lot for 6 months. Neither care whether either can do what you need done (towing the thing safely).
Because, well to be frank, that is your job.

If you have already taken delivery, your options are severely limited.
My grandfather had a saying in Italian that "loosely" translates as "Act in haste; repent in leisure."

I will take a look at your numbers and try to figure out where you stand.

OP the calculator used limits the weight to straight bumper pull & does not allow for the WDH rating to be entered:
Maximum Trailer Weight This is the maximum trailer weight based on the most restrictive tow vehicle ratings provided (tongue weight rating at 15% of trailer weight).
Your posted truck specs are well within what can reasonably be expected to tow the 2608WS. To be ure take the truck loaded for camping to the scales to see what your real numbers are you should end with more than sufficient capacity in payload for the expected trailer hitch weight

OK,
For the Rockwood 2608WS:

Dry Weight5675lbs GVWR6698lbs Cargo Capacity985lbs Hitch Weight698lbs Axle Weight4977lbs Exterior Height10.00' Exterior Length29.58'


With a cargo capacity of only 985 pounds you are going to be running that puppy at max GW just about every camping trip. So we will use those numbers for tongue weight.

With a properly adjusted WD hitch, your tongue weight should fall in the 10 - 20% of full camper weight. We will use 15% as "optimum" but with careful loading that tongue weight can be moved a little back and forth.

"Curb" weight on the truck includes JUST a full tank of gas and a 150 pound driver. You will need to add for the WD hitch; your family; and any junk you want to carry in the truck. (Generator, gas cans, etc). All of the is PAYLOAD (of which you have 2080 pounds available). So, using that number we will say your you weigh 200 and you carry your wife, kids and dog for a "meat" load of 300 pounds. Your hitch weighs 50 pounds. and you have nothing else in the truck (yea I know, gonna be more).

So "out the door" camping your truck weighs 5564 + 330 + 50 = call it 5950 pounds.

Payload available = GVWR 7700 - OTD weight 5950 = 1750 pounds available payload (tongue weight).


6698 is the maximum it can weight so the maximum tongue weight worst case 20% is 1340 pounds. Loaded like this, you still are OK

At "Optimum" of 15% tongue weight is 1005 pounds. Still OK
At Minimum of 10% tongue weight is 670 pounds. Still OK

HOWEVER you need to watch the GCWR of the "combination" as well.

Since we are running the camper at max what is left for the truck to weight? Using your figures (17100 pounds) 17100 - 6698 = 10, 402

So the truck can weight 10,402 pounds WELL and safely over the trucks max of 7700 pounds.

So you can add about another 400 pounds of "stuff or people" to the truck and not exceed your safe towing range by my numbers.

So if I got the camper right, you are seriously " GOOD TO GO!"

Safe camping my friend!

I agree with Herk's calculations.

I'd say you are very close but ok with this setup using the changing gears calculator.

I used the same calculator with your numbers (missing the RGAWR) and it comes out with a maximum trailer weight of 6,769 when I used a 12% safety margin and a 13% tongue weight (15% TW is the maximum for a travel trailer and I find that 13% works well for us YMMV). See below.

Your trailer has a very low CCC so watch what you load.

What does the yellow sticker say? Weight distribution hitch, propane, batteries, a little water and cargo will quickly fill that up. Do not overload.

Need to start taking Ginko Biloba.
9%-15% is the range for Travel Trailers.
Trying to keep all these numbers in my head is causing leaks...
