I agree with 77 .. HCV's last for years on heavy duty trucks. However , I'm sure Newell is aware of the dire consequences of a HCV failure so they change them prophylactically . I would be quite disappointed if I had burnt the paint off of a newly painted coach as well as doing tire damage when my HCV failed. It seems to me that the body could be engineered to allow the coach to move without tire and body damage if the bags deflated.
