On the '15+ Ford recommends 25% FALR. A lot of people recommend more I've played around a bit with my '18 with tongue weights between 700 -900 lb and found my truck is less "skatey" with less FALR than more. IE 40% FALR feels more stable than 80%. Has anyone else found this to be the case?

 

What is FALR?

How are you calculating FLAR? CAT Scale or measurements?

 

You can do either. Spring compresses a a given rate per inch and your looking for percentages so measuring works.

 

I agree you can do either but I was just wondering how he calculated it based on his experience that he is reporting.

My thought on this is you really need to be at a CAT Scale to see what is going on. Sure you can tweak settings (easier with some WD hitches than others) but you might be transferring weight but not see it as easily if just doing a measurement to a given point on the truck. While I will do the measurement trick, for me it is just to see that the weight is being shifted forward as more of an estimate so I know I am good to drive the 20 miles to the closest CAT scale to me. Not that I go to the CAT scale every time I hit the road but I do if we make a big change in how we are towing. For instance a change in truck or other pretty significant change. I am going to make a trip there pretty soon as we are going to clean out the camper from our "normal stuff" for a trip to Yellowstone over the summer. We want to go on a big diet for that trip. Also I added airbags to the truck so that is a substantial configuration change meaning another trip to the scales. While the scales are 20 miles away, it is about a 2 mile detour from our normal trip to where we go camping so I will periodically do a spot check if something ever felt off or I am curious as to how much stuff has slipped into the camper over the years.

 

I used CAT scales to get 1/2FALR
I thought I read it was supposed to be 1/2 so that is what I set up for. Seems to work fine

Measurements

 

My 15 & 18 Owner's Manuals had 25% or technically "1/4 of the way down from H2 to H1".

My older trucks had 50%.

 

This is how I do it. Truck, truck with trailer no bars and then again as I tune the bars.

When I use the measure method in a parking lot or driveway. I don't get any change in front measurement when unhitched compared to hitched with no bars. Then I start adjusting how many links I am hanging to where I see the rear going back closer to unhitched height and the nose starts to dip a bit. That gets me to the CAT Scale.
