i went and looked for a model # and found a plate that has two numbers one is 3820155 the other is 18827-F-1 I'm not sure which is the model number because the black paint is mostly gone.

No, not all fuller transmissions are Roadrangers.
A Roadranger transmission, which is made by Eaton/Fuller, is a twin counter shaft transmission with a 5 speed box and at least a two speed box all made together. The 5 speeds are shifted with the stick, and any range or splitter shifts are by air cylinders.

Fuller also makes single counter shaft transmissions (up to 6 speeds I think) all controlled by the shifter. These would not be called "Roadrangers".

Those numbers don't tell me much. The model number is the important one, it should have something like RT-#### or RTO-#### or RTOF-#### (the #'s are for numbers like 9510, 6610, or similar.)
