I am confised. I don't see how the tow vehicle could affect the ball height measurement with the frame of the trailer level (horizontal with the ground). Are you refering to the different height of the entire trailer due to the different amout of gear loaded into the Casita?
I am just trying to determine what I need to do to get my TV ball height in the vicinity of correct (i.e., an inch or so higher than the Casita-level coupler height w/ no weight on it) so when the trailer is hooked up and the TV suspension settles a bit, the trailer will be fairly level.
any measurement we give you may not work, the proper measurement is when your trailer is hooked up and ready to go and each towvehicle drop varies depending on the suspension.
Great, that is what I need.
Is that with the standard or High Lift Axle? I imagine the high lift raises the ball height by an inch or two over the standard?
Just curious, did you weigh each axle to determine how the weight got distributed?
Yes, 20.5 is the ball height for level Casita. You may have to select a different ball platform/draw bar dependent on how much your tow vehicle settles when Casita is hitched.
On the Escalade we use a ball platform/draw bar with a two inch drop. The escalade suspension returns the Casita/Escalade to level with the standard air adjustable shocks. The hitch weight of 450 lbs. was distributed 500 lbs. on rear suspension and -50 lbs. on the front suspension.
The hitch is rated for 500 lbs. without WDH and 1500 lbs. with WDH. I started using a WDH to lighten the load on the air adjustable shocks and transfer more of the hitch weight to the front suspension and Casita axle. I haven't had our rig weighed to see how much the weight distribution has improved. I will do this at the next available opportunity.
