It's Friday so bare w/ me.....

Besides carpet, has anyone had a good experience, that they'd like to share, about working on top of gravel.

I need to replace rear wheel bearings in my 1985 Vanagon and have no place to work, except nice flat gravel spot!

I also am thinking about issues of jacking van up with my jack in gravel, not good!

Thanks for any insights.....

PS.  Sometimes, yes, I'll concrete as needed but today I'm stuck w/ gravel so help me if you have knowledge.
