We just got a new pop up trailer and pull it with a toyota sienna. This new trailer when fully loaded is at the max of the towing capacity of the van. On my truck the towing tables show at what weight to add a weight distribution hitch. The van just says max 3000lb. When the weather clears up I want to take it to a flat parking lot and measure how much sag the trailer causes and how much rise I need on the hitch to level it out. So how do you determine when just air bags or helper springs are needed versus a WD hitch?
I would also be concerned about the word 'max'. Just cause one can don't mean one should.
So please take into consideration load rating of tires are the P rated or load rate D or E?
Is the transmission a CVT? Are they known to have any normal issues that can be amplified by running a full towing capacity?
Do you have a local grain/feed store near you? Some of them have a free public scale which means you can pull up with your loaded trailer and find out what you're really dealing with. If you go to eTrailer or someone else looking into a WDH they want to know to the best of one's ability all the weight numbers to get the correct set up.
If you're OK with all that then by all means enjoy the camper!
on edit:
"So how do you determine when just air bags or helper springs are needed versus a WD hitch?"
air bags and spring helpers help with sag and may be great for pulling tractors, equipment etc. but a TT is a tad different.
You are pulling a box of sheeted plywood for a visual. the WDH helps move some of the weight to the front wheels which helps with loading the wheels for steering control.
The ball is a pivot point and the wind whips the trailer pretty hard versus equipment where the wind is not blocked like holding up a sheet of plywood.
So with towing at full max a WDH may be the best option to ensure the load is spread to the front wheels for steering control.
Hope I didn't confuse the both of us still on my second cup of coffee.
