Isn’t that a second gen. Tacoma?
I have a cap for a first gen. for sale here in NH. Not your model, not your size, not grey or white, not near you, sorry.
I bought a gray ARE camper shell for my 1st gen Tundra. The bed on a double cab and the extend cab are about an inch different so the cab off either size will fit. I put a double cab shell on my extended cab and you would be hard pressed to tell.
@redfishnc Thanks for the heads-up. I read on a different forum that people were having trouble getting them water tight with the "wrong" topper. I guess it is dependent on the model of shell.
p.s. Your truck looks good.
