Default Hitch Height

Is there a formula on what height/drop or rise is correct????

I had a 2" drop for my previous boat which was to much for my new boat...sitting low and holding water in the bow while driving up/down the highway.
Flipped it over to a 3/4 rise and it made up a bit of difference but still feel it should be higher...
Was out at a store and saw a 3" rise,can this be to much????

Is there more down force/tongue weight the higher you go?
Am I over analyzing this to much?

Thx for your thoughts & advice.

Mike

some of it depends on your trailer height. but the rule is 17-19" from the ground to the top of the ball. I had a h2 that had a 6" drop. now the truck has a 5" drop

trailer should be as level as possible when hitched to truck. if the boat is on the truck, go to a flat parking lot and measure from the bottom of the trailer frame near the toung to the ground and at a point back towards but in front of the wheels do the same (using the same reference point of hte frame). The difference in these measurements will approximate how much more lift on the hitch you need. this assumes that the trailer is properly set up for the boat already.

Yep a level trailer... I actually have 2 different hitches for my rig, one for when the truck is loaded heavy and one for it empty... On a tandem or tri axle it is extra important, want the axles to have uniform loads

Like the other's have said, level as possible! If it's not, your best case scenario is it's going to eat the tires that are on the axle that's taking the greater load.

If your Bow is low when hooked to the tow truck, set a level on the trailer frame then measure from the frake [ At the hitch ] to the ground .

Next , set your trailer jack and commence to jacking up that baby up .

When the level reads level [ or lust a tad high at the hitch ] measure again .

The difference of the two measurements are the ball height you need.

And of course this is all done on flat ground.

Default This is the answer. If not you will put uneven pressure and wear on other axles?

Even on a single axle you want the trailer level although its not near as important.

Striper In;

I had the same problem with my boat on the Aluminum tandem with torsion axles. I opted for a B&W "Tow & Stow". It ran me about $175 but it's an excellent universal hitch for my boat and work trailers It may seem expensive but if you have to tow more than one trailer it pays for itself by the time you get hitches for each set up.
