I've looked around on truck forums and haven't found great info, so I am hoping someone here has some experience with this.

I want to mount two locking fork mount racks directly to the bed of my truck. Either in the flat bottom of the bed or on the back rail (which is metal). Anyone done this? Is drilling through the paint/metal (for bolts) or screwing through the paint/metal (self tapping screws) a bad idea? I've read that I should use rubber washers and then a silicone seal/caulk around the actual edge of the rack.

And I don't want to mount them to a board or anything like that for two reasons...so don't suggest that.

Thanks in advance for any advice.

this is totally fine and there is nothing wrong with mounting yakima locking blockheads or thule locking lowrider racks with this applications. we just talked about it here, and don't see a reason to seal the outside of the block with silicone, or use rubber washers. i don't see it being a bad idea either....not doing that wouldn't be a dealbreaker for me.

maybe someone else has some insight why they would suggest that that i'm overlooking??

if you were going to nut it on the under side, you could use a little primer on the drill hole.

just make sure that where you mount them, your handlebars and pedals wont' interfere with the cab or wheelwells and you mount far enough forward to accomodate your wheelbase.

Thanks for the reply -- glad you think it is okay. My main concern was inviting rust. The places where I saw that suggested it was as an effort to keep water out.

rust would be my only concern. if you self tap, you might find over time that it will rust. if you can nut it on the underside, you'd have a chance to prime the drill hole before install. this is a good reason for mounting it to a board or using something like the thule locking bedrider.
you mentioned you didn't want to go this route in your original post....but this rack, albeit a little bit more expensive, is fully locking, and if you mount it about 5" from the front of your bed, is a good place to store the front wheels of the bike. it's not permanent, and can be mounted high or low in most beds.

I forgot to mention just for good measure put a coat of rustoleum on the edge of the metal to prevent the rusting. the silicone should give a good seal but just for good measures..

also don't use self-tapping as it does have a tendancy to rust and rust whatever it comes in contact with. also the movement from the bike without tying it down would probably bend the metal

I bolted mine to the bed at the top of the back ofthe bed to make it easy to get the bike from the side of the truck. I used grade 5 bolts with nylon lock nuts and washers and sprayed some rustoleum on the drilled area. Worked like a charm, but in my new truck I use a block of wood since this is a brand new truck

I for some reason have the hardest time to drill in the bed. even though i drilled in the cab for the amp and other things and lets not start in the engine. but I love those riv nuts
