Need advice on setting up?

Have a 22' Toyhauler I picked up and rehabbed last year

http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27609229/srt/pd/pging/1/page/1.cfm

I've been borrowing a 2500 to tow it with from buddies until now. I just picked up a 2014 F150 Ecoboost with 3.55 gears and towing package. Rated to tow 9800lbs.

***Disclaimer. Yes I know I should weigh everything and have that data, but i don't at this time so work with what I do know here.

I have planned on a weight distributing hitch. For grins and giggles I backed up the truck to the trailer today. Measured the body height unladen and then with the truck supporting the trailer.

With trailer on the hitch the front raised approx 1/2" and the rear dropped 2 3/4".

I was surprised that the front only raised up 1/2". I was expecting at least 1.5-2".

Will the weight distributing hitch ease up the rear sag I'm seeing?

I know it will transfer weight to the front but since the front isn't really raising much should I be looking at rear suspension help(ie airbags) first?

Thanks for the help

    Can you elaborate?
  • I think that is pretty normal. The weight on the hitch will primarily compress the rear springs. The primary pivot point is the rear axle but with all the engine weight on the front axle it's not going to let that rise very far. But when you force the weight forward with the WDH it should come back into balance...

  • well that seems to be what mine did too

    my hitch is curt with anti sway bars 600 pound ones(trailer is light 4100 pounds dry.

    think about the total weight at each axle front, rear

    front axle heavy ie engine their :) rear light . ie no load
    ok hook up trailer rear loaded, ok so now we need to find a good
    balance of front and rear axle weights ie too heavy on rear front steering feels soft and floating so to speak \this is not good for breaking/ stopping / steering ..if you cant steer or stop quickly if the balance is off.
    i set mine up with my trailer loaded and water in the tank
    also you want a little sag in the rear( truck) so to speak..
    the trailer tongue needs a little slope down.. is if it's too high you get wagging trailer (sway back and forth )
    just trying to help,,, also my English is bad .
    and to add another wrench in the mix i have air bags on axel. i put just enough air in bags for contact of the stubby leaf spring
    ( truck has 3 leafs 2 long ones and stubby one that their for weight in bed) factory springs.
    also i have it set up to the level on the trailer bubble just sloping towards the truck a little.. think about leveling a site for fridge example you want to be in center of bubble well towing i want a little towards the truck on the bubble. = no sway :)
    hope i helped, just things to think about.

    Only a WDH will return steering control. And Yes, It WILL correct the rear sag. By the time you get the front back down where it is supposed to be. The rear will come up close to where it started from. AND the entire thing will drive way better.

    The WDH IMOP is the way to go for safety, and control


    Definitely will be using a WDH, just wasn't sure it would address the rear sag much.

    Thanks
  • In truth 1/2" rise will take a couple hundred pounds off the steering axle. that will make the steering axle light, and easy to turn. that will cause sway. Air bags, or any thing else you use to stiffen the rear will NOT return the steering control to the steering axle.
