i have a 2001 340 Fiesta Vee. The waste holding tank has suddenly buckled in the centre almost like the suction is too powerful when pumping out. Has anyone else experienced this issue?

Bottom line is that the vacuum suction will vary from pump out station to pump out station and this is not unique to Rinker - I've seen it happen on several other brands. I had the same issue and and in 2010, I installed:

This has worked out really well and is super easy to install BUT you should continue to monitor your tank during pump-outs to make sure that the valve is sufficient for your tank. Even though the Big Orange has a vacuum breaker valve, it is undersized for the amount of air that needs to get drawn into a 40 gallon holding tank to ensure the tank does not start getting sucked in. Mine has a permanent dent in the top from this happening before someone on the old forum brought it up.
