I'm doing some home improvement, and have the necessary skills, tools, etc, for the job. There is one thing I'm lacking: a large pickup truck for transporting lumber. A buddy of mine used to have one, but he had to trade it in for an SUV to get the kids to/from school, sports, etc.
I have a fairly large SUV, and can buy an aftermarket cross-bar roof rack. I've tied down some mid-sized items in the past while camping, but I'm a bit concerned about how I'm going to transfer a few large items from Home Depot:
- A 5/8" thick
x8' long MDF particle board.
- 16 2x4's, each at 6' long.
I think I'll have to do two trips. The planned setup is documented below (pardon the obscene number of pictures), and I plan to essentially run web ratchet straps (with band protectors where it comes in contact with the wood) to hold down the load to the cross-bars, and then an extra 20' web ratchet strap along the length of the load to act as a fail-safe. I'll have to drive maybe 20 minutes at highway speeds, and am concerned, especially in the case of the MDF board, of the payload catching too much wind drag and being pulled off the roof (ie: acting as a big parachute).
Does the setup below look sound? I'm not comfortable enough with my knot-tying skills to go with a hitch in place of the web ratchets, unless there are some dead easy knots I could use in place of the ratchets. I do not want to pose any risk at all to other drivers, so if I need to invest in additional hardware to secure the lumber, that's fine with me.
Also, if I can find a working approach for the lumber project above, I also need to transport a glass door plus frame about 400km at highway speeds, and was wondering if it would be viable to fix it down to a large piece of plywood similar to what I'm doing above.
Thank you for your help!
My Car with roof rack with cross-bars installed
My car with 4'x8' MDF board on the roof rack
4 web ratchet straps in a pair of X formations to hold down the board to the cross-bars
A pair of 20' web ratchets used as a fail-safe, in case the board slides to the rear of the vehicle
Second trip, 16 2"x4"x6' boards on my roof rack
3 ratchets for holding the bundle together, 4 in X patterns to secure it to the cross-bars, and a 20' ratchet along the length of the bundle as a fail-safe
I'm getting a pair of stainless steel tow hooks installed on my vehicle tomorrow. The current little hook on the rear of my vehicle doesn't have a large opening, and the one on the front is a joke, as it just screws on, so it's easy to steal. The new ones will be bolted on the vehicle without the bolts being exposed.
I'll continue using my roof rack with the advised ratchet configuration to secure them (ie: the pen-and-paper plus elastic example in the accepted answer), and using a large 27' ratchet wrapped around the length of the load, and secured to the rear and front tow hooks (with thick protectors where it touches the car chassis) to keep the front of the planks from flapping upwards and either snapping off or acting as a parachute. Plus, it gives some extra security in case the friction from the other ratchets isn't enough. Thanks everyone!
