With Harbor Freight I would create a safety margin and buy more than you need. If you need a 1 ton engine hoists, get the 2 ton, etc. I bought the 2 ton foldable engine hoist. Some of the parts (the support bars) needed persuasion when first building it as they didn't line up 100%.
I tried torquing some bolts to spec and the head broke off. So they definitely need to get replaced with grade 8. I also noticed that some of the bolts like backing out. So I would put red loctite on them and check them each time before use.
I've used it around 25+ times now over rocky ground and it has held up pretty good.
HF 2 ton foldable engine hoist with HF load leveler attached. And HF 1000 lb wood dolly functioning as a transmission dolly.
HF isn't that bad. You just need to read reviews about what is worthless and what is actually good. The cheap china engine stand I bought from Summit looks like the exact one from HF.
