Hi fwh, I did go with the Bilsteins. I got the 4 for the front as Steve suggested, I am most probably going to get the 4 rear as well. I did a lot of research and spoke with a Bilstein Engineer. On my MH the only leaks that were found were on the front. I was told that these should last over 100k. I imagine that a bad seal caused the leaks on the original.
If you go with the Bilstein Make Sure you get the latest version.

This is from a Spartan site, they had the Best price. For my MH a 2001 Dynasty the number was BE5-F629-HO. The number for the 02-06 should read BE5-F628-HO Not B46-1724-P2 Those numbers are the Old Numbers with the wrong valving.
