Average pin weight?

[mdamerell]

I've often read that a 5'rs pin weight, on average, is 20-25% of the trailers weight. Personally, mine runs around 22%. Do most people find this rule of thumb to be accurate?

Reading a thread on 1/2 ton towable 5'rs, the one person posted his numbers and his pin weight was around 16%. Got me to wondering if the 1/2 ton 5'rs run a lighter pin weight? Since most 5'rs will hit the pin weight limit before the tow limit. Is this one way the manufacture's are making them towable with a 1/2 ton truck?

Don't want to start a war, just an honest question.

If his pin weight is 16% it is a product of
1. wishful thinking
2. poorly loaded with too much weight behind the axles
3. a poorly designed trailer with the axles too far ahead.
Our 24.5' without a slide grosses at 5600 lb, pin weight comes in just shy of 1300 lb which is pushing the limits of any F-150/1500. Such a truck will pull it, many people do, but the experience would not be enjoyable or safe. We started out with a truck that was marginal for our needs, won't make that mistake again.
