I now have a couple trips under my belt with my 27ft camper tailer.

I had the RV dealer install a BlueOx Sway Pro at the same time I picked up the trailer.

I also have LoadLifter 5000 air bags.

I was still not happy with the tow, especially in any wind.

The trailer was not swaying behind the truck but the entire setup would wander spontaneously. It felt to me like turbulence in a small airplane. It was a white knuckle experience above 60 mph.

Anyway I spent some time sitting by the campfire reading the forum and learned a lot about the crappy OEM tires and air pressure and decided to try putting the air pressure up to the max 50 psi for the ride home.

To say it was an improvement is an understatement. The ride was so much better I found it hard to believe. It eliminated the turbulence and the ride is now safe.

I wanted to thank everyone who participates in the forum. This info is priceless and you can’t get this type of advice from most dealers.

I planned on buying some BFG TA KO2’s when these tires wore out but it looks like I might upgrade sooner.

Cheers.

First thing I do when getting ready to pull our TT is air up the TV tires to Max (44#).
Second thing is check the trailer tire pressure.

I have the same setup as you and have towed my trailer in the signature with 3 different F150s now.

While you will stiffen the side wall, you also decrease the tread that meets the road if you air them up to much.

I just purchased the Blue Ox as well. Here's my recent review of the truck, trailer and blue ox.

BTW, your Avenger 27DBS is a super long 33' not 27'. Trailers that long are usually recommended for 3/4 ton trucks because the length and side wall height make them a bit much to handle in the wind as they are a rolling sail.

Many here have reported changing to LT tires helps sway considerably. Since you say the sidewall max pressure is 50 psi you may already have LT tires.

New Goodyear Wrangler Fortitude HT tires have a max pressure of 51 psi for their (P)assenger Series Tires.

LT tires should get you a little more stiffness but you will probably find you need a little more air in them. I think they are more durable. They are heavier. Mine are about 55 lb each tire only.

With my heavier 2012 F150, doing the chalk test, 47 lbs was the correct air pressure on the LT BFGoodrich All Terrain T/A KO2 tires. Also after talking to BFGoodrich, they said 47 lbs was the correct pressure for the same load handling as the OEM Passenger tire.

Now for F150s of that same generation with the same size 18" C rated tire, mine were Load Rating E (10 ply), people were saying that the door jam sticker was saying 41 psi. That pressure would equal less load rating than the same size P series tires at 35 psi. BUT the truck likely didn't need that much load capacity and for that tire, it may have been correct for proper tire wear.
