My short list for a toy hauler purchase is either an Epic 3990 or a Grand Design 397 TH. Over on the Grand Design forum several folks have had issues with the hoses being used in the plumbing, either leaking on the PEX fittings they are installed on, or the hoses are busting. The hoses that are busting are pretty much all hot water hoses. Both cold and hot are leaking. There is a mixture of PEX pipe and these hoses being used in their units. Some of them have taken it upon themselves to change all of their hose over to PEX. I will say that Grand Design, even though they say the hose is up to standard and continue to use it, has reimbursed them for the cost of parts to change to PEX. I will include a couple of pictures of busted hose from them. Does anyone know if this hose is being used in the Voltage toy haulers and if so any problems with it. I am REALLY HOPING they use all PEX.
I have a Voltage 3990 and been all over it with nothing resembling that hose.

From the installation manual for hose similar to you photo:
"a double-barbed fitting held in place with two band clamps appears to be the best choice"
Was it a double-barbed fitting? Certainly didn't have two band clamps.
Nope they are installing this hose on the same plastic PEX fittings as the PEX pipe with the same single PEX cinch rings. To be honest I was leaning towards a Grand Fesign because I felt their customer service was better and the insulation under their garage floor. But this hose issue kinda changes things. Thanks for the replies.
