Question:
We have a 2023 Grand Design Solitude 390rk which has 7K dual axles under it. Has anyone ever installed the Timbren silent system on one of these?

Hey Jerald! I can't say I have heard of anyone adding the Timbren Silent Ride Suspension # TSR14KT01 (33" axle spacing) or # TSR14K35T01 (35" axle spacing) to their Grand Design but I'm sure some people have done it. This wouldn't be too different from the independent suspension system Grand Design adds from the factory on some models of the Solitude.
What we usually see Grand Design owners buy, and what I recommend, is the Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570. This uses slipper springs in a unique configuration to give you an independent suspension system. It also comes with their shock kit. The combination of the two adds the best upgrade out there. We have installed this system on quite a few Grand Design models which you can see in the installation video below.
Any big trips planned with your Solitude this fall?
