What dorp do i need to pull a boat trailer and for it to be level?

Don't listen to H2gayperson. First, some things need to be established. What size boat, type of trailer tongue, does it have surge brakes, etc.

If you have the rear air you don't need to expect the rear to sag any. If not, you need to think about how much tongue weight the trailer has.

You can't simply just go to walmart and get a hitch. Many of the hitches are designed for 5K pounds or less. You would be better served to go to an RV store and talk to them about it.

WTF is this measuring crap about?????? Subtract 5"??????

The drop is the difference between the bottom of the lip of the tongue to the top of the inside of the receiver on the truck.

Dude, don't give out information on things you don't know anything about.

Paragon is right on, the amount of drop required is dependent on three factors:
1)Level height of the loaded trailer tonque to the ground
2)Tongue weight of the loaded trailer
3)Loaded height of the vehicle's platform hitch receiver, assuming you have the factory frame mounted hitch.

Towing a trailer safely should be a priority, not an afterthought. Have a professional assist you if you are unsure about anything. The Hummer you save may be mine.

If your info was so dead on, why did you delete your posts? I am glad you admitted you were the idiot at least I'll feel better when I keep pointing that out.

For others that don't think they know it all. Surge brakes on a trailer require the tongue to mounted on top of the trailers frame. The average trailer that does not have surge brakes has the tonge mounted inline at the apex of the trailer frame. A surge trailer will require a shorter drop hitch than the same trailer if it didn't have surge brakes. That would be what surge brakes has to do with ball height.

Boat size goes to tonque weight which is a deciding factor if you have rear springs. A trailer with 750lb tongue weight is going to set the rear of the truck down lower than a trailer with a 100lb tongue weight. It's all really very simple, but H2GayPerson seems to be here only to be a ****head.

So again, don't listen to him.

None of that effects the height of the ball on the truck you need to think about it for a sec there Captain Brilliant. What boat has over 1 or 200 lbs tongue weight? I can lift the front of my 22' boat trailer by hand man. Its like 150 lbs. Trailers are designed that way bro.

Sport, sorry your experience in life has been so short, small and insignificant. I've pulled many a boat with tongue weights in the 1,000lbs+ area. The heavier the boat the more tongue weight that's needed to keep the balance right. You can't just have all the weight on the trailer tires or it would fish-tail you all over the road.

Give up on this, you don't know your ass from a hole in the ground here.

Im sorry thats just not true. A boat is balanced on its axels not on the hitch. OMG already get a clue.

What are you talking about?

Skippy (sorry Seth, it fits too well), don't tell me something that I have a lot of experience with is not true and what does "balanced on the axles" have anything to do with what I said.

If a 14,000lb boat is "balanced" on it's axles then it is safe to assume that more weight is on the tongue than a 4,000lb boat. Rule of thumb for others who car. Boat trailers are designed to put around 10% of the total weight on tongue. H2Gay, can you do that math?

Who here actually thinks boat trailers are balanced on the hitch and not the axles? Anyone?

The question was generalized. Its not about that anymore anyway. hehe

http://www.sherline.com/lmbook.htm#refrn9

Single Axle: 10% minimum - 15% maximum
Tandem Axle: 9% - 15%
Travel Trailer: 11% - 12%
5th Wheel: 15% - 25%

Trailer Tongue -- This is the next boat-trailer component that Greviskis talks about. It's the long piece (see photo, right) that goes all the way down the boat trailer, from the coupler on back. The perfect weight distribution for the trailer tongue should be eight percent of the total boat and trailer weight combined.

Ok so whats the average trailerable boat weigh? 6000 lbs? So about 4 or 500 lbs tongue weight? My boat supposedly weighs 6500 lbs. I can lift the front by hand.. How is this possible?

Andre, this may help you. Then you could switch trailers and easily adjust the hitch. The pic is just one example.

That was my first recommendation and I still got flamed.
