Howdy man, glad you chimed in, i though Tony and I where the last inhabitants here
Yes but no on the nutserts -I think... they won't sit flush with the panel and I don't trust them t.b.h, different story if they went into a fish plate also ...
That was my first thought but I want to sandwich the roof panel as much as I can and nutserts sit too proud from the panel for that..
Regarding the chanel section, your right it would be the strongest part of the panel BUT
it would be a p.t.a to work with- channels to narrow for sideways support and getting bolts into them would be impossible. Also, any bolt rivet etc would sit lower again and would definitely hit the head lining...
And then there's the issue "and a major one" of water pooling! So no, wont be going near the chanel..
I'm thinking where I have them is the go! Good run off and plenty of footprint as they say... It scares the "poosnwees" out of me drilling into the roof, imagine if the danm thing leaks!
It should still get some support from that chanel section and the nuts won't be an issue on the internal... I won't really know "how to go about it" untill I get the headlining out.. lots of thinking before that happens bloke
I'm thinking nut and bolt and "not using panel washers" but a full length fish plates, "IF" i can get them into where they need to be...
I'm re thinking the mounts now lol front ones ok but the rear two I'm thinking of making one! Bigger foorptprint onto the roof!
Then again, it's only going to be carrying 100kg tops, what's 60lt of water weigh?
