ive been looking around and trying to find the most inexpensive sturdiest way to mount my homemade rack using gutter mounts, pics would be awesome!

I'm also looking for some inexpensive gutter clamps. I've seen lots of old work vans at the JY with latter racks on top, thinking I could get some from there.

that's a good idea, I was just there the other day pulling a center console, but how well do you think those would hold up weight wise?

I just used some aluminum angle iron

I have a conifer rack that is pretty heavy duty. I essentially have one piece that hooks under the rail from the inside, and that bolts and clamps to a piece that goes on the outside of the rail. The rack is mounted in between these two pieces. Inexpensive and solid as a rock. Hopefully this gives a a good idea.

I attached my home made rack with jcr gutter mounts. Not the cheapest route and as soon as I got them i realized I could have made my own at work in about 15 min but I don't mind supporting good vendors.

yeah i was thinking about going that route because i dont think i would trust myself to get the right angles or the strength

For my 48" wide rack the angle ended up being 70.5 to fit in the rails, but please dont make yours to that spec without first measuring
