If you are going to be removing the camper between trips, adjustable air bags are really the only way to maintain acceptable ride quality and compliance both loaded and unloaded. Paired with adjustable shocks if possible. Air bags are easy to install with the camper on.
We got talked into Sumo springs for our Troop Carrier (long distance; it was in Australia and we were in the U.S.) I disliked them intensely. They support a load okay but steal compliance. I'll be removing them soon and installing a proper spring pack that supports the load and retains compliance.
