Sorry Rick, what you are asking has much more to do with how you pack, then the trailer. It is a good rule of thumb that the tongue weight
should be about 10% of the total, loaded weight
of the trailer.
If your stuff is ahead of the axle
, the tongue weight goes up, if it is behind, then the tongue weight goes down.
Things on the tongue, like batteries, propane
tanks, spare tires
, (that's what is on the tongue of my Trillium
4500) will add to the tongue weight. I needed to increase my tongue weight, because I put a 500 lb cargo platform on the back of my trailer. This, by the way, is considered to be a bad idea. Excess weight behind the axle
makes for an unstable trailer. It worked out for me though. Those Trillium
trailers seem to be fairly stable.
Ideally the cargo should be ahead of the axle
with as little behind the axle as possible.
