increasing tongue weight

There are limits to how much you can do it, but a lower tongue will increase percentage of TW.

Weight centered over the axles will add 0% to the hitch weight.
Weight added directly over the ball will add 100%.
Between that it's basically a percentage of the distance between...so 50% of the distance between the ball and center of axles will add 50% to the hitch weight.

Now if you can move weight from the back end to the front end, that can actually result in greater than 100% as weight behind the axles actually reduces hitch weight. So if you have a generator on the rear bumper and can move it to a rack above the tongue, that can have a bigger impact.

If it's towing well, I wouldn't put a lot of effort into it but do keep an eye on it...especially if you have a trip where you will be carrying fresh water. It might not take much to push from towing well to being a problem.

Well, ya gotta describe what characteristic you’d like to improve or this is just a poorly written mystery.

Not really having any real issues towing, just feel (in my head) that a little more tongue weight would make a better tow. Trailer tows level. I have front bunks and their loaded with gear, and my front storage is loaded. Have thought about getting an a frame bike rack just to add some weight. I would have to add 110lbs to tongue weight to get up to 12%, which sounds like im gonna have to add approx 200lbs to achieve that. Planning on getting new trailer next year, so this may be all a moot point, thanks everybody for the replies.

Add an extra battery and install a carrier for a generator or storage box on the tongue.

Consider adding a couple more batteries in a box on the tongue. Box and batteries will total 140 more pounds pretty far forward. Carry your bicycle on top of the box.

If your trailer is not experiencing any issues with sway then I'd just leave it alone....tow level or slightly nose down which would give a seesaw increase in tounge weight.

If you set on more tounge you could always add a cooler up front or add to front storage.

12 - 15 % seems to be standard but you'd have to show me an issue with towing before I'd delve into the numbers.

Teeter-totter knowledge comes in handy. If you add 100#'s 1 foot forward of the axles, you might increase the tongue weight 10 pounds. If you put that same 100#'s at the front of the trailer, you might add 60-70#'s to the tongue weight.
