Towing 8,000lbs with RCSB - numbers
My latest tow ended near a state weigh station. I went through it and jotted the axle weights down. After unhooking I returned and re-weighed the axles.I paired those measurements with what my vehicle is rated for, sourced from https://www.ford.com/cmslibs/content...F150_Oct15.pdf
GVWR can be found at https://www.ford.com/trucks/f150/models/f150-xlt/ Axle weight ratings are from my doorjamb sticker. https://cimg1.ibsrv.net/gimg/www.f15...1ca9ea4da4.png Tongue is 15.5% of trailer weight. 'F150 sans Bigfoot' is the weight after unhooking. It's the raw weight of the vehicle, plus campershell, half tank of gas, myself, tools, the bicycle that's still in the back, and whatever else i normally carry in the truck. It's the sum of the front and rear axle weights from the 2nd measurement.
Tires - I believe stock tires work fine for towing and their load rating is factored into the GAWR. I am on my second set of tires, and they are LT with printed load ranges 50-80psi. 50psi is way too stiff of a ride when not towing (for this truck). Door stickers says 35psi for the stock P rated tires. So I run 50psi when towing, and 35psi otherwise. I have towed at 60psi and it felt more jostly at times. Curious if any rcsb's ever shipped with LT tires, and if so what the suggested psi on the doorjamb is. Tires are Nokian Rotiiva https://www.nokiantires.com/all-weat...tiiva-at-plus/ Trailer tires are stock and set at 50psi. Ride feel - The wheel well height lowers about an inch once the wd hitch is adjusted. It feels good towing to me, but I upgraded from a Tacoma. I know people who come from Super Duties, and some aren't comfortable with the ride difference. On the other hand, the guys at TFLTruck do tow heavy loads, with both Super Duties and F150's, and if these videos are to be believed, aren't bothered, and sometimes prefer, towing with the F150:

Performance - The 2.7L performs great, and there are plenty of tow reports about this engine. I did tow over Siskiyou pass, the highest point on Interstate 5, heading south. Going uphill I got stuck behind semis going 40mph. When it was clear, I entered the passing lane and bumped the cruise control back up to 55mph. There was no drama and I was quickly up to speed and able to pass. Descending - There was zero engine braking. So your trailer brakes MUST be adjusted and monitored. Be mentally prepared to reach over and control your trailer speed by hand with the squeeze control everytime you descend. Monitor your tow status screen as you tow, and observe output to the trailer brakes on the gauge. I say this, because I have had my brake pedal decoupled from the trailer brakes before. I didn't catch the problem until I was on the road. Squeeze lever trailer brakes still worked. A restart of the vehicle fixed it, but needless to say, I watch that tow info brake meter like a hawk now. I will occasionally glance at tire pressure, but otherwise the tow status screen is what's on the display while I'm towing. Fuel - The manual recommends using premium fuel when towing. I believe the engine likes it - for example the fuel consumption gauge after filling with premium shows a 4-8mpg increase in fuel economy! (unladen - I always fill before I hook up) I haven’t tested this, it’s just something I notice everytime I put premium in. In 3 years and 950 miles of towing this load, I average 12mpg.

Thanks for sharing, always nice to see data like this with sources:thumbup1:!

Looks great. Nice trailer.
|
Thanks! I changed the post to include raw measurements, not just the derived data (trailer weight, tongue weight etc)

jdriver, great write up. I have a 2018 rcsb 5.0 4x4 3:73 gear 6400gvwr. My truck came with load range E tires 17". I run @ 46psi when empty, much easier on back ; ) . Travel trailer were looking at (Outdoors RV 21RD) is close wt and length wise to yours. Been looking for real world info on how these rcsb's tow. How's it feel in cross winds ?

That's great hudman. I've been looking forever for that sticker!
I hit 20mph winds on my latest tow, just yesterday, 150 miles or so. That was the most wind I've driven in while towing. The only thing I noticed was, twice I had to do relatively quick steering adjustments, seemingly out of nowhere. This is with the ProPride hitch, which has an sway solution, where any movement from the front of the hitch processes without resistance (I can stand in front of the trailer and swing it freely left and right with my hands) while at the same time, physically locking the trailer to the hitch in the rear direction. So no sway transmits from the trailer to the truck. I've been looking at it for years and don't know how it works, but it works! Traditional friction style sway control is a different beast, where your vehicle has to overcome it to for example make a turn. I'd say the most important thing, is weight distribution. You don't want to your headlights pointing at the moon! i think a good wd hitch is more important than the tow vehicle, because no matter the tow vehicle, you gotta get that weight off the rear axle, distributed some! |
I dont think there is a 5th wheel on the planet that is light enough for your truck.
Maybe there is. But generally you need much more payload for a 5th wheel. |

Not all fifth wheel trailers are 12-14K beasts requiring a dually. |

Just google the trailer he referenced

Not all fifth wheel trailers are 12-14K beasts requiring a dually. I did say "maybe there is". 1100 lbs of pin weight is going to maxing out a non HDPP truck though. For example: My trucks payload is 1535. 1100 pin + 220lbs myself and I am already at 1320lbs. Not a lot left. In all honesty I would still tow that with my truck. |
IF you can crank the bars a little more you can send a little more to the front and off the rear, but pretty close.
With the PP you will have no issues, those quick driving adjustments you mentioned would be constant with any other hitch. Hensley and Pro-Pride are the way to tow. |
