More fuel for the fire:
The Hamilton form Hallmark is discontinued. I asked the current owner to call and find out the empty weight. They told him about 2400lbs dry.I could not read the number on the placard because it was sort of worn away. What I did see I think was in kgs. I will call myself and get an answer.
Truck wt. with me (183lbs.) and a full tank- 6750
Front axle- 4400lbs.
rear axle-6040lbs.
GVW-8800lbs.
Max tire load- 3986 at 80psi.
Sounds like 80psi will be required because of the weight.
Thanks for the response. I will post more latter.
