I feel dumb posting this, but I searched and couldn't find an answer. I'm trying to mount my 10 lbs bottle on the passenger side corner of my trunk. How are most people mounting their brackets? I'm assuming self tapping screws. If so, about how long? Not trying to poke holes into anything that doesnt need any poking. Thanks in advance!

 

self tappers work their way lose...I suggest/used bolts or carriage bolt with lock nuts.

 

So I can just drill a hole, drop a bolt through the trunk side, and tighten it with a nut from under the car? Last time I looked under the car I could have sworn there was something in the way, right above the muffler. Thanks.

Mine is there but the chassis rail gets in the way. If you're careful you can get one of the holes to line up with a hole in the chassis rail to get a nut on. Not ideal but I have an 11lb bottle there using this approach.

Although I'm tempted to make up a steel plate for underneath to spread the load a little as the boot skin is so thin there.
