I have 3, one is in the body work and paint stage and the two others are for sale. I figured it took me 8 years to get to the stage I am at with the 48 GMC and I have the CE waiting to get back to a driver, so no time for the others.
The 51 I started with never got too far off the ground before I found the 48. I just started collecting them and parts for them that I got distracted. I ended up with 4 suburbans and three Canopy expresses, I have been slowly getting rid of them and holding on to just two.
