Essentially what I've been doing. HD rental truck. But truck availability and requiring multiple round trips to return and pick up my car means I put it off until I'm blocked, and then needlessly stock up on sheet goods that I might need in the future, but ultimately sit around for a year or two before I use them.

But yeah, this is what I'm doing while I bide my time for truck prices to drop. And I've push back a bunch of projects that rely on ply because I just don't want to deal with the hassle.

To your point, I bet the trailers are probably more readily available. The trucks themselves are very hit or miss in my experience. But there always seems to be trailers in the lot.
