Can I Drill and Screw Here?

I'm replacing the round 4" sewer hose holders with one made from a square 5" PVC fence post. I'd like to mount it up against the front wall of the grey tank. The pan under the tank and the tank are held in place with a galvanized bar running from right to left and galvanized straps running front to rear. The bolts/lag screws holding the straps also go through holes in the bar, using only every other hole. I presume they go into a frame cross member.

Is there any reason why I couldn'tt use two of the unused holes, drilling into the crossmember, to hold my new hose caddy?

I would be using much smaller hardware, probably #12 or 1/4".

Thanks,

Al

I drilled and tapped a frame cross member at three points to install my sewer hose holding tube, and can't think of why you couldn't as well.

Thanks guys. I couldn't believe how the existing tubes were installed. One side of the legs of one tube was screwed into a frame member. The other side of that tube's mounts and all four screws of the other tubes mounts were mounted to the belly pan only. Three of the other 6 screws had front or rear mounted backing plates but were still free to flap around with the belly pan.

Yup, when I added mine, I made a an aluminum plate of thicker skin material, about 3" X 3" and put in place with 4 olympic rivets (to displace the weight over a larger area) and then used expansion nuts to attach the tube foot to the plate/belly skin. One of my tubes contains a cylindrical water softener and a PVC stand. Total weight....22#s. Has held fast for almost 10,000 miles now with no visible degradation of material.

I did also add two PVC pipe hangers on that one as well, screwed to the cross member.
