my parts van is slowly descending into the earth, and I'd like to keep it above. Concrete blocks aren't really suitable for long term support, IMO, but I'm not sure what better options there are. Maybe RR ties? Ideally I would keep it high enough that the tires don't deflate completely and separate from the rim, because there are times when I may want to move it. Any proven ideas? The ground is a bit soft where I have it because its on the north side of my house and it doesn't dry out completely. But there is no appropriate place that's dryer. August will probably be the last chance I have to jack it up with dry-ish earth, if it isn't too late to get a jack under it already.
I'm liking the RR tie idea that I just had while typing this, but will post it anyway in case someone can do better. I can probably scrape up a RR tie on my property.
