How can you tell if the turbo is working properly? I heard a whoosh sound in engine bay during climb and the RV started accelerating as if turbo kicked on. Lasted for about 30 seconds and then seemed to quit, causing RV to slow to 15 miles an hour on interstate. Any info or similar scenarios with solutions would be appreciated.
Thanks in advance!

Do you have a turbo boost gauge and an exhaust temperature gauge? These will give you an idea of how well you turbo is working.
It sounds like a turbo waste gate or similar problem if it pulled good for a short time and then back to low power. Also could be an exhaust brake sticking on or blockage in the exhaust system.
Many years ago, I had a customer complaining about occasional low power and it turned out that one of his intake system hoses would suck in flat when he worked it hard! That was a real head scratcher for a few hours of test driving. Finally we put an intake vacuum gauge after the air cleaner, that's how we found it!
Happy Glamping.
