Advice on using air bags with a WD hitch

We’re about to take delivery of a 2018 FC 25FBT
that we’d like to pull with a F150 3.5 Ecoboost SuperCrew 4x4 that has a GVWR of 7000 lbs and currently had a total load rating of 1863 lbs according to the door label. It also has after market airbag suspension assist on the rear.

I haven’t bought the weight distribution hitch yet but was leaning towards the Andresen.

I’m also adding solar and lithium and hence can move the batteries further back in the trailer to shift more weight off the hitch. Normally I’d put them under one of the the beds but could put them over the axles if really necessary.

My question is this. Since the the truck already has air bags, should I use them in some way when settting up the WD hitch or just deflate them and let the hitch do what it does?

Second question would it make sense to upgrade the truck’s tires from the stock Goodyear 275/65R18 116’s? Would that give me more load capacity?

Before the purchase of an Anderson or any other hitch, do extensive research. Understand what it will and won't do. Specifically, understand the trailer coupler requirements for the Anderson hitch. Good luck with your investigation. Pat

Post 18 in the link below is HowiE's. He has considerable info on the Anderson as he reports lots of practical experience.

For what purpose are you purchasing the airbags?

I have a ram truck with airbags and found that 15 lbs works good with the equalizer hitch
I use about 7 lbs when not towing

The truck had the airbags from when I had a much lighter trailer. They were great in that situation when we were doing a lot of serious off road driving in that it allowed the trailer more freedom of movement over rough roads. It was was also easier to hitch and unhitch.

If I was starting our with the 25FC I wouldn’t have bothered with them. Now that they are there, though, I was wondering if there is any utility to them as I am pretty close on the payload side with this truck.

Best to let the WDH operate w/o interference.

The WDH should be able to restore the front axle solo weight value, something the Andersen isn’t known for once TW gets above 400# (good luck finding scale tickets in evidence).

A WDH will take 20%+ of the TW off the TV when set that way.

And axle limits are what matter. “Payload” is pretty much what’s carried in bed, rear axle; not applicable.

What did you notice improved when adding those 8 lbs?

My AS dealer likes to install the BlueOx SwayPro hitches. Should I take his advice instead of the Andersen?

A BO isn’t the best, but theres naught worse than an Andersen.

You can use the air bags just don't have them making up for improper hitch set up.

Set them to the minimum pressure or 10 PSI and then do your hitch set up and measurements as you would with any spring suspension.

If the settles more than 1" at the back you need more pressure on the torsion bars not more air in the bags.

Set up properly you will not have any load capacity issues with an F150. They are a well proven tow vehicle, thousands are using them over many millions of miles I have yet to see any issue ever due to load capacity.

If you like send me an email and I can send you a couple of sheets on how to configure your weight distribution properly. On your combination we would use a 12 or 1400 pound Eaz-Lift weight distribution kit with 2 friction sway controls, We use Reese snap ups because the Eaz-Lift ones have a poor geometry so they are harder to connect. We use our own hitch shanks because the Eaz-Lift ones are now Cast Iron which we won't use.

I hope this helps.

Andy

I tow with a 2015 F-350 diesel and use the Andersen hitch with a '01 Classic 30'er. I am very happy with it and have used it over 6 years now and lots of miles. It works well with my combination. Last year we had solar installed and moved to the lifeline AGM batteries and moved them inboard below the front couch. It reduced the tongue weight by 80 # so if that was your goal it might work for you. I went from 880#TW to 800#. Don't expect any greater reduction.

Merry Christmas to you and hope to see ya on the road sometime.

I sometimes use my air bags for taking the trailer to the dump station if at a park for more than a week. It is only slightly less work than installing the WD bars. The help raise the TV rear to help avoid striking the tongue jack when going over large dips or potholes in the road.

I have used Reese, Equalizer, and 3 Blue Ox hitches over the last 13 years, towing 3 different-25' AS's (with an F150 EB)and now have a new 28'FC (with an F250). The Reese worked fine but was a hassle setting up. The Equalizer stabilizer bar broke when backing up shortly after we picked up our 2008 25' AS. I replaced with a new Blue Ox; only one dealer had in stock. Worked great next 2.5 years. When I got my 3rd 25'FC few years back, I chose a new Blue Ox with 1000lb bars and it worked great for the 3 years I owned it. I have a new Blue Ox with 1500lb bars for my current 28'FC. I am very pleased with all around performance. Great hitch for the money, easy to set up once you learn proper set up, and provides good Weight Distribution and Anti-sway protection. So many hitches, so little time! "Best" is a matter of opinion.
