I have a Host Mamoth on ram 3500 with wood wedges and Redline airbags (7500LB 150PSI AIR BAGS). I like this setup, I like aibags to raise and lower the rear, it drove fine 1000 miles. It is a big rough when empty, but drove great with camper on it. I am going to remove the wedges and load the camper and see how it handles. I had no isses loading a 5k camper with these airbags and the wedges, handling was great when loaded up to 110 psi. Many swear by only having torklift stableload, they might be correct. Will update later.
