I have a 2019 gasser and daily it 44 miles. I also tow a 31' TT to the lake and back 10 times a year plus have a 19' Rinker thats towed double that. What worked for me is 60psi front and 55psi rear when empty and Bilstein 5100s (even the stabilizer), no sway bars. I can't complain about the ride at all. I do use Sumos on the truck (I have the shorter version they give for free upon request if you bottom out too much when empty).

anyone know what the air pressure threshold is b4 the light comes on? Carli recommends you run below 40 psi I think,

I changed mine to 40 with Forscan, not sure what it was from the factory.

I suggest Kenda 35x12.5r18 Klever RT on a Method HD with +18mm offset. 35-40 psi. Same front/rear psi should reduce understeer.

Fox 2.0 shocks.
Stiffer Plow or Diesel front springs, if youre blowing through front suspension travel. I run the plow springs, truck is taller than most.
Remove your sway bars.
Fox ATS steering damper.
Hydraulic or neumatic bump stops are likely a bad idea at this point. Theyre generally something that needs incorporated with custom 2.5 shocks.
Any scary scenarios without the sway bars? I may try this too.

I like my ATS damper too.

Its easy to work with. I take before and after photos of what code I am messing with incase of a typo. Pretty straight forward.

Also put a good steering stabilizer on it and replace any worn front end parts. Helps quite a bit too.
I will look into that thanks!

I was thinking I was ready for a new vehicle, but then thought, I'd really like something that I can have fun with off road and still drive it on road most of the time. That's how I got to Carli Pathfinder.

The last time we went to MOAB, I thought the family was going to walk half way in to Canyonlands on Potash. We are going back this summer and I want it to be a different experience. Having the front end completely sorted, and tires that are capable of being aired down will mean a different experience, and more opportunity to explore.

Good luck with your build.
Sounds like you made a good choice! Should be fun to test out and compare to your last trip there. Lol thanks im hoping it doesn't turn into a build but we'll see!

I will look into all those as well. As far as tires i definitely want different ones. I have Nokian Rotiiva at plus that were on the truck when I bought it. There ok but definitely more of a street tire compared to other ATs I've used in the past. They are also 80psi fill. Would like to get away from that.

I think i decided im going to get the Bilstein 5100s. Seems alot of people like them and help with towing better than softer shocks like Fox. And price wise isn't bad at all. I'll look into the Sumos and the sway bar removal.

Fox aint any softer, than Bilstein. Unless you mistakenly bought some custom tuned "gas engine version" that some idiot here, insisted on creating. I prefer the Fox's right now.

With only a measely 8 inches of up travel, these trucks need as much compression damping as possible.

Ok ill need to do some more research with that then. From my research i havent seen anywhere recommend them when towing. But could be they are more branded as an offroad shock vs Bilsteins. I do have a gas so stay away from any "gas" versions?

Just the normal version from Stage3 or Shock Warehouse, will do.

Its just more expensive than the base model Bilsteins. Might be why the fudd brigade is on them so much. The 4600 is the cheapest decent shock for these trucks.

It will also lower it around 3/4”.

I have ran all the shocks mentioned here and the rs7mt rides the softest. I have read there is also a Monroe brand monotube.

Yeah. The fox2.0 are a performance shock. They eat up the bumps and corners.

That doesn't mean they are the smoothest riding shock.

I liked my Fox2.0 on my old F250. About to install Falcon on my current project f250.
