Letting the combined weight of 15M lbs gather momentum at 60MPH takes a lot of braking effort to slow down.
I have been on downhill slopes where I had to keep the speed at 30MPH.

Keeping it slow downhill is smart. Don't know how to calculate it, but it seems the energy needed to slow from 60 to 50 downhill greatly exceeds that to slow from 40 to 30.

Your observation is spot on. The kinetic energy of a vehicle in motion is directly related to the vehicle mass AND directly related to the squared of the vehicle speed. The energy that must be dissipated by brakes to stop a rig going at 60 MPH is 4 times that of a rig going at 30 MPH. I have seen posts in this forum where members claim the stopping distance with a trailer in tow is the same as TV solo ("The trailer brakes stop the trailer"). This maybe true at lower speeds but not necessarily at higher speeds.

Al, I don't think I did a good job of explaining myself. I am doing the same technique as you and my reference to leveling was to my truck. Sorry for being confusing.

Is your truck an XLT, Lariat, or Platinum, ...?
Thanks for providing the photos.
Ron

Ron, mine is a Lariat.

ClydeCrash, I have a 2013 f-150. Love it, however, being pre aluminum body, the payload limits are relatively low and that is the most restrictive. The truck will pull, weight wise, anything in the AS line but when you drop the trailer tongue weight, with a hitch, you have very little left for peeps, any stuff in the bed, etc.

As a 10 year old boy I used to spend summers at my grandmothers farming town. I remember sitting up high on the hay wagon and watching the horses struggle to hold the wagon back going downhill and my uncle locking up the brakes. I was always worried sick about the horses getting rolled over by the runaway wagon. This mental picture flashes in my head every time I begin a scary downhill ride with our Airstream. It keeps me disciplined.

I have a 2013 F-150 EB with a tow package but not the Max tow package. The maximum tow rating is 9200 lbs. The power is fine but sometimes I get blown around a bit (big trucks and side winds). I always drive about 60 mph. I've heard that various suspension enhancements will help. I'm confused about Airbags, Super Springs, Roadmaster Active Suspension, heavier duty tires, etc. Can anyone enlighten me?

Changed tires to LT from P series. LT tires have thicker sidewalls. Less sideways flex. Slightly harder riding but help with side sway.

I got mine installed at DNW here in Jonesboro. You can get them with or without an air compressor, I chose with.

You don't need any of that crap if you have a modern weight distribution hitch designed by Hensley, now sold by Hensley and ProPride. Put all concerns about being pushed around to rest, as well as any sway concerns. Your factory tires are fine, air to maximum sidewall pressure for towing and hauling, and will give you and your Airstream a better ride. Don't overload the axles or tires (verify it with a trip to the CAT truck scale with your rig) and this w.d. hitch will help ensure that.

LT tires, particularly when the stock P rated tires are worn anyway, are a heck of a lot less expensive, heavy, or as fussy as those fancy hitches. Made a world of difference on my F150 towing a 30 with bone simple Equalizer.
