What "trim" is my truck?

I have a 2010 TRD Off Road Tacoma with V6 auto tranny, Access Cab, long (6'+) bed SR5 etc. I am looking at a new Access Roll Up Tonneau cover on ebay for just over $300.

In the ordering instructions it asks if my truck has the "base" "prerunner" or "x-runner" trim. I've heard of these before, but how the hell does my truck fit into the scheme as far as what trim to choose?

Last, this cover retails at $500+ and normally sells for $400+ but its on here for $316 plus free shipping, too good to be true? Anybody have experience with this? Assuming it's legit the cover seems to be one of the best available. Here's the link in case anyone wants in.

PreRunner.

 

Prerunner

 

I don't know if it depends on the trim rather than if you have a long bed or a short bed

 

A lot of sites require you to select Pre runner. (Even if you have 4x4.) Make you sure select the proper bed size, that matters more in this case.

 

AC only has one bed length

 

I swear I read through that and didn't see AC

damnit.

 

thanks

About the price - keep in mind ebay is one of the primary places counterfeiters sell their illegal wares. And not just cellphones and handbags are counterfeited anymore... You can find a fake imitation of just about anything these days.

 

go with truckalterations for tonneaus, their prices are great. There's a link on here for toyota discounts.
