2022 DYNAMAX ISATA Complaints

This unit is a cutaway Sprinter converted to a class C RV by Dynamax Corporation. I discovered a propane leak and in tracing it down, found that Dynamax had run their main propane delivery over a flexible hose. This hose was improperly protected from being damaged by poor installation process in that the hose was strapped to a cross member under the unit without consideration to protecting the sheath. I have just over 20K miles on this and the main sheath has a pinhole caused by it rubbing against a sharp edged metal cross-member. The cross-member is directly under the passenger compartment exposing us to fire and gas exposure. This danger could have easily been avoided by either putting a protective sheath between the hose an the cross-member, or plumbing the entire length with black pipe. I consider myself fortunate that this leak did not present itself while driving down the road. I have attached pictures of both the cross-member where the gas line is strapped down and the pinhole in the gas line (verified with a propane tester).

Tire Pressure Monitoring System is very unreliable. Right rear wheel rarely reads. TPM readings are typically off by over 10psi verified with calibrated gauges when cold.

Valve stem on inner rear Dually tire was delivered with a loose nut causing it to loose air.

Constant Electronic Stability Control failed not allowing use of adaptive cruise control
