    I am going to do it myself. I’m going to use a step bit and tape off the 3/8 mark to ensure I don’t go past it. We’ll see how everything goes once I get it!

    Just be careful with the stepper bit, if you go too big you are screwed. I got the correct bit and a stopper set at 3/8" depth. I just pre-drilled all the holes per side then used the bit. It takes some effort too, the roof is kinda thick.

    Lots of shenanigans.
    I have the Leitner bed rack and decked system and seem to never have enough storage. I plan on running a prinsu rack for another light bar and additional storage room. I personally don’t care about drilling into my truck because I’ve already done it a bunch of times. Good thread though with lots of good info

    It’s the 95L. It is pretty bulky and might get the 83L since it’s more Low profile

    Also, I did my first hole at 9" from the window seal and the "scary" holes missed the side airbag just fine. I would also get a few extra bolts for doing the inserts, it can mess up the threads after a few uses and they will not thread back in without spinning the insert loose. Ask me how I know?

    I also used black Permatex Silicone Adhesive Sealant quite liberally, don't be shy with it.

    Good to know. Do you remember what size bolts they were? The install videos that I have seen said to measure 10 inches from the window seal. Did you go 9 inches just to avoid those “scary holes.” Thanks for the info!

    Too many, but not enough....
    Spider roof racks are a no drill option that can be removed.

    I cautiously drilled my roof and installed a roof rack myself, it wasn't really that big of a deal with some forethought and preparation. Due to the good people who post on this forum I had read all the threads regarding inadvertently drilling into the side curtain airbags prior to purchasing and installing my rack. I didn't buy the Prinsu but went with the vilified Victory rack for a couple of reasons, but regardless the danger of (over)drilling the roof and into the airbags remains the same no matter which rack you install. For that reason and in the interest of self serving over-caution, before drilling I pulled down the edges of my headliner in the area about to be drilled (without actually disassembling the headliner) and felt around to judge the amount of clearance between the roof and the airbags. I gently pushed down on the airbags to flatten them and increase clearance as much as possible. I then took a piece of 1/2" inch thick x 2" wide aluminum flat bar and laid it on top of the airbags beneath the drilling locations as I drilled each set of holes just in case I accidentally over drilled a hole. I used drill stops set to around 5/8" inch depth on the drill bits and carefully drilled the holes. By going slow I was able to control the drill pretty well and the stops "bottomed out" the drill bit without slipping and prevented any over drilling.

    It's daunting to drill into the roof of an expensive new truck, for sure. But having the rack and the options it gives for hauling my kayaks, Maxtrax, WaterPort, etc. made it well worth the extra effort to do it safely and without incident.
    The process I followed is located on my "build" thread starting with post #15.

    I measured and marked the hole locations, and installed drill depth stops on the drill bits to be used.

    Topper 03.jpg
    Dropped the sides of my headliner to inspect and have access to the side curtain airbags.

    This is the 1/2" thick x 2" wide aluminum flat bar I laid over the top of the airbags prior to drilling the roof.

    I watched a few install videos, including their own and they all had different measurements. So I called and asked, was told that you can do anywhere from 7 to 10 inches, whatever looks best to you and it should be okay. I went at 9, I thought it looked best to my eye.

    Update: Installed the Prinsu Rack along with a 50” Diode Dynamics light bar.

    It was a very nerve racking installation, but the end product is definitely worth it.

    I installed prinstu on my taco pro and it looks sick. But now with my 21 tundra pro I definitely became a chicken sh*t when it comes to drilling.

    how many inches does this add to the top of the truck? I have about 6-7” clearance left in my garage. Want t Prinsu but also want to make sure I can still tuck her in at night. It looks like I should have room

    How much height does it add to the cab? I have an AT Habitat camper with a similar hangover to the GFC.

    Also, do you think you could drill the holes with your camper installed? Or is there not wnough clearance for the back holes under the hangover???

    I’m almost there. I used a set of collar drill bit stops but those stupid things kept sliding down the bit. I ended using a wooden dowel and drilled down the middle of it.

    I’ve got one side set with the rivnuts. I just need to drill 4 more holes on the other side.

    Did anyone come close to the plastic weather channel clip on the rears? Mine were almost to the clips. I triple checked the measurements at the front by the windshield.

    Yeah, the last hole is really close to the weather strip clip. I measured 9 1/8 for the first hole. Anything more than the last hole will definitely be where the clips are.

    I measured the same per the instructions and video. It was a little too close for comfort so I ended up taking the clips off so the rivnuts could sit flush. I don’t want to take any chances with water leaks.

    I got the other side drilled tonight and will be able to get the rack on later this week. Hopefully I’ll be able to lay down the sealant properly the first time. I have to measure up the weather channel molding and cut it to length. I originally was just going to drill through them but they’re not rigid enough for the drill to pass through.

    Nice! I didn’t remove the clips, but I know it was really close. No leaks at all with the rack. So as long as you seal it correctly you should be good. I cut the weather stripping to length around the spacers. It’s definitely a nerve racking install all the way around, but you’ll love it when it’s done.

    I have the uptop overland rack on my cap...basically did it for more lights not for hauling...avoided over the cab because of drilling and I have plenty of forward facing lights. The uptop overland rack is built like a tank and well engineered.

    Finally finished the install on it. I took a lot of measurements before hand to make sure I would still be able to park inside the garage. After I finished it, I was a little nervous just from eyeballing it. I ended up having about 3” left. Whew!

    Love the way it turned out. The drilling was worth it. Like everyone said, take your time. Measure 10 times, drill once. I did what @TampaRD Pro did with a small plate to block the airbags. Ended up not needing it after all because I made my drill stop and checked underneath before drilling. Once you drill a couple, the rest are easy. I was a little paranoid about leaks so I used a lot of the silicone.

    Very happy with the quality of the rack.

    I’m really curious about what you plan to do with the rack - if you are okay since you still have 3” clearance to allow you to get into garage, what are you going to use the rack for? I mean they doesn’t exactly leave much room to put anything on there. Will it only be ‘day use’? (Meaning, something goes up there while you are out, but comes off once you get home?)
