WANTED: Ideas to build locking storage box for SUP's for top of motorhome please

[magentawave]

I'm going to be traveling extensively and want to carry and store my SUP's (12' and 9'-10") and surfboards on the top of a Class C motorhome but I want them out of the elements and reasonably secure from theft so I was thinking of building a big white low profile rectangular locking box for the boards.

Does anyone have any ideas for building something like this? Have you seen anything like this? Any links to photos of a box like this?

Thanks

Steve

Just throwing out some thoughts here:

Big cruising yachts often have fibreglass deck boxes and also similar boxes on docks.  Perhaps check out some docks for manufacturer names as they are often from local shops.  Then get a custom set built. 

Fishboat builders for aluminum boxes?  Who makes those tool boxes on pick-up trucks?

Make them oversize for when you get bigger boards.

Make the internal supports adjustable/removable for versatility.

Leave room for paddles and stinky wet suit booties? 

Consider air vents and drain holes.  You might want some sort of drain system so salt and sand don't remain on the vehicle.

Make them have a reflective top or at least white colour so they don't heat up as much.

Could more than the top fold over?  That way access might be easier and accommodate oversize gear.

Internal tie down points?  You don't want stuff bouncing around even if the lid is closed. 

I have no idea what a Class C motorhome is, but I assume its tall.  Will the boxes' height dimension be a concern for going under things like overpasses, garages, trees?

A Class C motorhome is the kind that usually has the van front end and a section over the cab for sleeping.

Hey thanks for lots of good ideas! Yes it would be white for sure and I'm thinking it will open from the back so there is less area exposed for possible leakage and also because I'll probably install solar panels on top of it.

That's pretty easy to design and build. I'd probably do it with 1/4" ply, perhaps with a layer or two of fiberglass. And hinge one side and whole top for easy access (makes a bigger arc when the side is hinged to the bottom). You could still do the photocells. Gas cylinders to help lift and hold the top. Easy.

Have you ever seen anything like that? I also want to build something for the back to put my mountain bike in if I don't get a Class C.
