Never at the level I now see as wheeling.
However, around my high school year family had an '84 Sub wagoon. Had low range, adjustable height suspension. We used it as our hunting rig for a number of years on some fair rough dirt roads and trails. Did very well in snow, had about 12" ground clarence. Was pretty fun.
In college I drove a '78 Brat. Mod dirt roads is the worst I had the chance to take it on.
I like the idea of a SAS Brat! That would be too cool!
