The other option is to adapt a motorcycle stand but I don't have the tools to do such a thing.
I ride motorcycles.... They all would require some ability at welding/brazing to modify the frame.
In fact,
I am leary of any kick stands that use clamps - especially if I'm running heavy. (Last trip was at 80+ pounds.)
The problem is clamps can lead to bent stays or subtle movement of the entire rear triangle under pressure.
A common mounting point for heavy bikes has been clamps below and over the stays where they meet the bottom bracket. The clamp eventually flattens the stays a little and the kickstand loosens. Continued tightening eventually results in flattening and weakening of the stays at the weld/braze with the bottom bracket. ( If you have a Surly Trucker, Surly makes clamps that can be used for this purpose without flattening the stays.)
If you have an old mount brazed under the stay at the bottom bracket - or have the money to get one brazed on (see photo attached), this 2.5 pound, $70 center stand - similar in design to what's used on heavier motorcyles - might be what you are looking for. Photo below of what that mounting bracket should look like.
(Meanwhile, it's OK to lean your bike against a wall or tree or equivalent.)
