Hi Steve,
Welcome to the forum. Sounds like you have done a good job of researching your truck with the goal of keeping it original.
I believe that 4800GVW was for all 3104 trucks. (?)
6.00X16 tires were standard. 6.50X16 tires (RPO 282) were optional with heavy duty rear spring. 15" tires RPO 273 were also available.
1954 RPO numbers:
> RPO 282G = five 6.50X16-6ply front & rear (includes H.R. Spring) - 3104 without side mounted spare
> RPO 282K = three 6.50X16-6ply rear tires only (includes H.R. Spring) used with standard front tires, - 3104 without side mounted spare
> RPO 282M = five 6.50X16-6ply front & rear (includes H.R. Spring) - 3104 with side mounted spare
> RPO 282P = three 6.50X16-6ply rear tires only (includes H.R. Spring) used with standard front tires, - 3104 with side mounted spare

I'm looking forward to answers about the paint color of the mirror arms and heads.
