Pretty sure you can put it up on a table if you want to get it off of the floor. We've put one on a truck tailgate before.
So the main dealer for this company here is like a Watson's (of Watson's Girl fame) place that sells hot tubs and stuff. I went to the one relatively close to my place and they didn't have one on the floor so the guy goes and assembles one for the floor and is pitching me on it. I instantly see what I thought already - that the legs would kind of suck, both in shortness and how they spread out behind and in front of the thing. He tells me it's $450 but on sale for $381; he'd seen me looking at this thread and the thing on amazon and said there'd be no warranty if I bought it online. Told him I'd take some measurements and figure out what it could sit on and if it would work.
Ran the rest of my errands down south including a place that sells all Traegers and confirming none of their sizes would be as good as this thing or a vertical, and then had to go to the next-to-dirtiest dirt mall to get something from the container store. While in there, saw they sell "commercial" metal shelving -
https://www.containerstore.com/s/shelving/metro-commercial/12 - that would be a perfect 18 inches deep and I could get it to any height, but I can probably find something more industrial and less interior-looking for cheaper.
Trying to leave this mall, I see what looks like all the crap from the hot tub store out in some fenced off area of the parking lot. It was the same chain having some weekend event there. I tell that dude what I'm up to and he offers me the thing for $329 like it is on amazon and pretty much everywhere and says I can take it back to a store if it doesn't work out. So that's that.
What should I get that will be good and safe to put it on so that I can keep it 16-18 inches deep rather than the 23 the legs spread out to?
