FWIW, two thumbs up for the GoWesty Fox shocks.

My van came with Monroes, possibly from ~2013 or so.  By 2016 I had
blown them all out (leaking oil) from rough driving as you described.
Put on the Fox shocks then, and they're still going strong.

I swear when I purchased them, they came with lifetime free rebuilds,
but I don't see that on the listing now.  Hope they'll honor it....
