Expecting to get an F250 next summer. I want a box cover so that I can put some stuff out of the way and locked. Nothing that would resist a thief's effort but enough that someone can't just raise it and look what's under.

I also saw that they are not the same vs what they cover and what other things you can use with them. I would like some way to fork-mount 2 bikes just above the cover.

Any good place I can see what's on the market and what will or will not work with a bike fork mount system. Also waterproofing is important.

 

Diamondback truck covers......a little pricey but nice. Had one on my 250. I just bought some Thule bike mounts and the holes lined up perfectly but diamond back makes a system for a bike. Nice heavy duty cover.

get the seal kit to keep dust out.

then go to buy a bunch of weatherstripping stuff to fill the rest of the holes and gaps that the seal kit doesn't cover.

you will thank yourself in the long run.
