Go find a circle track or road racer that has a set of four wheel scales.
It'll give you the following weights:
Gross with fuel
Gross with you in it
full & empty weights for:
front to back & % of same
side to side
I had it done at the track one night.
There was a guy there offering the service as a promotional deal for his race shop.
Cost me $30 to find out where I needed to move weight around.
It is worth the time & money.
