"I want the truck because I am tired of throwing 2 sheets of plywood and logs on my SUV roof".
You have an HPM in Kapaloei(sp?).
I think they charge a flat rate of $50 for delivery and free for anything over $500.
That may have gone up, but is cheaper than a new truck.
Never buy new vehicles!
I built a lumber rack for my dual cab Tacoma. It mounts in the support notches of the bed liner that are meant for 2x4 and 2x6 lumber which can support boards across the bed left-to-right about 6" above the bed's bottom. I made the long supports from 4x4 treated posts that are lighter than the regular pine versions.
It's basically 3 x 8' posts running from the back window to the tailgate above the top of the bed, positioned to support the left, right and center points of the sheet goods. I have a retractable cover for my bed, so it needed to have space above that. I created 2 supports for the rails that are connected together with a single 2x4 making it a 2-lag-bolt installation and removal.
Anyway, I can fit a 4'x8' sheet of plywood or drywall on the 3 posts supporting the material. The sheet goods protrude out the back of (and above) the truck bed about 3 feet (5' bed with 8' material). I use ratchet straps to hold the material down. I can close the tailgate, and other items can fit in the space between the bed and the sheet goods. Everything rides about 4" above the top of the truck bed.
All-in-all, it does what I need. Spent time making a prototype, using that a few times, then creating this improved version.
I have stacked 5 pieces of 4'x8'x3/4" ply and 3 @ 4'x8' sheets of drywall on this rack in one trip. No problems at all other than waiting for a HD employee to help load up! Each time I've used it and needed assistance, I've gotten compliments from the employees.
The rack is made of 2x4s except for the 3 @ 8'x4"x4" posts. Most of the joinery is done with pocket holes (using the "heavy duty" version of the Kreg jig and pocket screws), and wood glue.
If interested in the design, I can do a separate thread for anyone thinking of making one. I'm planning on a lumber run soon, so I can take pics then if needed.
