2008 chevy gulf stream B Touring SE 22 ft kitchen and bath in rear every time I hit a bump in the road I launch everything forward is there any thing I can do to the suspension to correct this prob...
If by porpoiseing you mean when you hit a bump the front end bounces up and down for a while then you need new shocks in the front of the MH. My 36' MH does that after about 30,000 miles and I replace the Monroe shocks on the front and it cures it. I've considered other brands but I can't find a cross reference or anyone else who makes a shock for my XCS Freightliner chassis.
