Real gas shocks have 360 lbs of air pressure. Bilstein is the top product. Monroe shocks are indicated by this instructor to be inadequate. Some RV mfgrs are now using good quality gas shocks. There is a very significant difference between fifth wheels which include shock absorbers in the chassis construction, and and those which do not.
Shock absorbers protect the suspension system, tires, and the life of vehicle.
But original equipment shocks are often good for only about 10,000 miles. The use of shock absorbers by some fifth wheel manufacturers is a good indication of a superior quality fiver. SteerSafe and SteerPlus are the two most popular products. They are okay, but often problems are really related to inadequate swaybar, shocks, or springs. Thus stabilizers too are a band-aid approach to steering problems, masking some other more basic problem with the suspension.
