Propex Heater Exhaust Pipe

[Justavan]

Fitting a Propex Heater under the rock and roll bed and wondering how do you run the exhaust and air inlet pipe underneath your bus so as they will not be ripped off or crushed when driving over the rough stuff????????
Also how to stop them getting clogged up with mud and filling with water when in deep mud and water.....?????........

There are things a lot lower than the propex pipes under there and you run the hoses facing backwards and slightly downhill.
If you are really worried though get a sheet metal fabricators to make you up a belly pan out of 1/4 plate and weld it to the sills between the axles.

clip to chassis rails and wine corks when wading no worries

there is a min distance for the inlet and outlet to be apart to stop it sucking spent gas back in.

Anyone know where to get this pipe? Mine were sort of corrugated and felt like cardboard stuff, but have got old and brittle and have fallen to bits. Never worked brilliantly and sucking in the old gas could be part of the problem.

Thanks for the tips guys. Looks like a protective cover plate will be best option for this install........
