Question:
What would be the best suspension upgrade for my 2019 Grand Design 351M? Ultimately 8k axles would be the best but Im not sure I can afford it. The Roadmaster comfort-ride looks promising as does the Center point air ride suspension. I will be doing it myself to save $. Thank you for your help.

Expert Reply:
If the suspension of your 2019 Grand Design 351M is currently in good working order but you want to improve what you have by making the ride quality smoother you could go with just the shock portion of the Roadmaster Comfort Ride with part # RM-2470. You'd want to measure the diameter of your axles though. If they are 3-1/2 inch like what most 8k axles fit then the correct kit is the # RM-2470. If they instead are 3 inch you'd want the part # RM-2460.
