'14 F-250 PSD/'16 Cougar XLite 27RKS Towing Sep 2016

6.7L Diesel...3:55 Rear Axle...Michelin M&S LT 275/65R20 LR:E (inflated to 70# ea)...Firestone Airbags 20# ea...Reese manual Slider...DW + 2 small fury kids and clothing/equipment for 17 days travel.

Weigh-In: Steer Axle 5220 lbs (max5600)
Drive Axle: 4920 lbs (max 6100)
Trailer Axle: 6260
Gross Wt: 16400 (max 23500)
(Truck was 140# over GVWR with passengers, full 26 gal diesel, 2x30# propane tanks, ~20 gals fresh water)

Trip itinerary: OKC to Pinedale, Wy...Pinedale to Cody, Wy...Cody to OKC
Trip specs: total mileage towed 2618 miles; total mileage unhitched 1862; combined F250 mpg for total 4480 miles was 13 on the nose. Towing involved many miles of headwind and sidewind at 15-20 mph with higher gusts. One tow day involved nasty rain, fog, wind etc. Lots of 6,7,8% grades up/down. Engine brakes great in Tow/Haul mode. All interstate driving in Tow/Haul mode with Cruise set at 65/66 mph.

Hope this helps someone...we spent about 200 hours reading/studying trying to find a good 5th wheel match for our truck. Would have liked to have stumbled on a post like this.

PS. I used the Pilot Charge Card and used the Truck lanes at all Pilot/Flying J Truck stops...don't care if diesel was $.10-15 higher; this was an easy and fast way to refuel (put in pin# and don't even have to go inside as you are billed electronically and pay on-line) and would do it again in a heartbeat!

Welcome to IRV2 !! Sounds like you had a great trip. Its always a good trip when nothing goes wrong. Your setup is real close to ours. A good matchup.

Sounds like an almost perfect match between tow vehicle and TT. That TT has GVWR of 10,000 pounds, and as your scale ticket proves, That is close to the max for your F-250.

It sounds like you may have had the spring bars on the weight-distributing hitch a bit too tight, thus transferring a bit too much hitch weight to the front axle of the truck. And you probably had the angle of the ball mount to the coupler on the trailer not dialed in to transfer more weight to the trailer axles. So work on fine-tuning the WD hitch adjustment and you'll probably enjoy towing even more.

Your goal is 20% to 25% of gross hitch weight distributed to the trailer axles, and 20% to 25% of gross hitch weight distributed to the front axle of the tow vehicle, leaving 50% to 60% of gross hitch weight on the rear axle of the tow vehicle.

Gross hitch weight is tongue weight (TW) plus the shipping weight of the WD hitch.

Three steps to determine if your weight distribution is in the ballpark:

1] If you have a tongue weight scale, install the shank and the rest of the WD hitch to the coupler and tongue of the TT, then weigh your tongue. (Note: the shank is not installed in the receiver hitch of the tow vehicle, but just onto the tongue of the trailer.) If you don't have a tongue weight scale, buy, beg, or borrow one. Or search on how to calculate tongue weight with two passes over the CAT scale. Here's my tongue weight scale:

2] Next, tie the wet and loaded trailer to the wet and loaded tow vehicle, but with the spring bars hanging loose, and weigh the rig.

3] Finally, tighten the spring bars to where you think they should be and weigh the rig again.

Simple math to determine the percentage of gross hitch weight distributed off the rear axle to the trailer axles and to the front axle of the tow vehicle when the spring bars are tight..
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 3.5L EcoBoost SuperCrew.
