I came in to suggest the same idea lol. I'm new to site, and must say I love how busy it is and how fast everything is answered and moved along. But coming from a stand point of just looking to buy a truck, navigating the for sale section can be hell.
Most sites I've been two have things divided into atleast cars/trucks for sale, and then a parts for sale section, and some even go further into CL/Ebay finds, part outs, etc etc.
Looks like the site had a good start with the first gen/ second gen sections, which would make it nice to find stuff pertaining to your truck, but looks like people don't use it nearly as much. I think it defaulted where you had to pick between 1st and second gen, it would clean things up nicely. And dividing sales of parts and trucks would be awesome too. Other then that seems like a nice site! Lookin forward to getting a truck and gettin involved in this place
