Well seems i have a issue with our OTR . She stopped working the other day in 112 temp so needles to say I need to focus on the repair . So after some reading and research here I found the circuit breaker tripped . Thinking I dogged a bullet i reset it and turned the air back on after warming the coach up a bit . So while I’m sitting there a few moments and nothing is happening except seeing the fluid in the glass moving around I hear a bang and smoke is exhausting loud and fast . Well after shutting it down and taking a closer look it appears the pressure split the hose to the left going over the fuel tank . O so much for a easy fix . Not sure what caused it but have an appointment Tues at a Prevost recommended shop here in St George . When repaired i will report back and update .
