Looking for any experience or ideas for what's best to use for a 1.5in lift on a 90' Townace 4wd pop top camper. Have only found a few of this van on the forum and so far none have put a lift on it, so no luck there.

Overall weight: 1850kg=4078lbs

Have read a bunch of the lift/suspension posts for Townace/liteace vans, any idea if townace camper suspension is same, but just with larger load shocks/leafs?
