Our engine is off for repair and we're going to replace the mount isolators. The originals were manufactured by VIP and despite being installed for 17 years, they looked great when I pulled them out. No cracking, sagging, etc.. Looked up and found three options for our RVs....VIP, Barry or Lord with VIP being least expensive. Called them and found out the plant had burned down and they were not expecting any availability anytime soon. These mounts were around $100 each. Next up was Barry mounts. Seems to me they were around $150 each. Lastly, was Lord mounts at $250 each! I would have put the VIP mounts in if they were available but since they weren't we went with the Barry mounts.
