Thanks for all the replies!

I guess there are a few things I should have added to my original post.
The GP has been updated to a TH400 and it has a newer GM booster and dual master cylinder.
The trailer is an open pit trailer but it was built relatively heavy. I don't have a clue what the actual weight is.
Also, just as a point of reference regarding my 'normal' or 'OK', most of the miles I have pulled a trailer were with a 1/2 ton pickup or, for a while, a 4x4 Ford Ranger. I didn't get 'fancy' enough to have brakes on a trailer until about 5 years ago. LOL

If I do this, I'm thinking of stiffening the frame with a a couple pieces of steel plate and modifying a receiver hitch I have. I have one of the weight distributing hitches for this trailer, but never used it because the truck didn't really seem to need it.
