More WDH Questions

I just purchased a new TT and need to upgrade my hitch. However, I have been getting some mixed info from sources outside of this forum regarding WD / Sway Control hitches. Similar to bak4911, I am looking for a good quality WD hitch, and preferably with a non-friction sway control that is appropriate for my new setup, and I would rather not purchase it from the RV dealership when I pick-up my new trailer in April, (I do not want to be limited to their products or pay dealership prices).

From what I have been able to find on-line, both the Reese Dual Cam and the Equal-i-zer seem to be very popular quality products, and I believe that I will go with a slightly oversize (vs. slightly undersize) rounded spring bar Reese Dual Cam as the rounded spring bars are said to be more active (springier) under load than the trunnion version and I would also like a little wiggle room if I really load up the TT.

My question is, “What are the variables for determining the proper spring bar rating for a WD hitch?” I have been told by some that the factory specified tongue weight + propane tanks and battery(s) + the weight of cargo in the TT that is behind the TT’s rear axle are the only variables, but others have said that it is the actual loaded trailer tongue weight + the weight of cargo in the TT that is behind the TT’s rear axle.
If it is the latter, which spring bar spec would you recommend for the following:

TT = Tracer 2700res TE @ 30ft 8in w/ a dry weight of 6000lbs and factory tongue weight of 614lbs + 2 x 30lb tanks and 2 x 6v deep cycle batteries (est. ~200lbs). I also estimate the normal load in the TT will be 1200lbs, for an estimated loaded trailer weight of 7200lbs.

TV = F-150 5.0L S-CREW w/ short box w/ anywhere from zero to 250lbs cargo behind the rear axle.

If it is the loaded tongue weight, I believe it would be based upon 7200lbs + 250lbs x 13% = 968.5lbs actual loaded tongue weight, which would require a 1000lb rated spring bar. If it is just the factory specified tongue weight + propane tanks and battery(s) + the weight of cargo in the TT that is behind the TT’s rear axle, I believe it would be based on 614lbs + ((200 + 250) x 13%) and would = 672.5lbs Tongue Weight and would require a much lighter spring bar. 800lb ?

Any advice / recommendations you can give would be much appreciated.

JKF, the spring bar sizing should be gauged on the maximum trailer tongue weight. With a listed tongue weight of 633 lbs., that is gonna probably be in the 800-900 lb. range after adding a battery, propane, and camping gear. IMHO, 1000 lb. spring bars might be your best bet.

his chart used to be listed on Etrailer, but I can't readily find it there now:

As far as what you have behind the rear axles on your F150, 250 lbs. will be a lot in the bed, especially behind the axles. But I understand where you are coming from, and the Ford Crew Cab, short boxes have the wheels toward the front of the bed instead of near the middle as in the 6.5" beds. Load as much of the cargo weight next to the cab of the truck as possible.

The big problem is gonna be keeping within the GVWR of the truck...unless you have the maximum payload option. Hang a 900 lb. trailer tongue on the bumper, and 250 lbs. in the bed, and that does not leave much at all for passengers.....maybe just the driver.

Chap is right on.

If you select a WD Hitch rated for the maximum gross weight of the camper, the bars should be properly sized for the load.

I got mine from RV Wholesalers and was very happy with it.

Don't forget to order the ball, drop shank and Lithium grease.

A couple of things:
The only true way to know your tongue weight is to weigh your trailer. Makes it pretty hard to order before you have the trailer...

Which leads me to my second point, most WDH set-up the bars can be exchanged if needed. I can upgrade my Reece trunnion style bars in the future if needed. or, for that matter, step down to smaller ones etc.

We started with 1K bars based upon published numbers for our trailer. But a trip across the scales showed we had more than 1100lbs tongue weight so went to 1200 lb bars.

Could not agree more. Your hitch should be rated for a MINIMUM of your camper's max gross weight and the bars should be rated at a MINIMUM 15% of THAT number. For example, if your camper's max gross weight is 10,000 pounds, you should have at least 1500 pound bars.

1000 pound bars are good for a 7,500 pound camper. If your GVWR is higher than that you need to go with the next size up.

15% of 7500 is 1125. This doesn't quite follow your 1500lb bar logic.
