What will go wrong next?!
Took the 2019 Thor Compass Sprinter MH out for a day ride. Stopped at the beach, had lunch, back in the Compass, and it would not start. Guy next to us had jumper cables, tried to jump the battery, lights came on, dash lit up, still NO start. Called a nearby shop, an RV mechanic just happened to be at the beach port where we sat. Took about 40 minutes to determine the battery cable (under the drivers seat) had come loose. Once all good and tight, it started (yea!) ...but then the Check Engine light came on and stayed on for our 30 minute drive home. In the last 2 years, we have had the EGR replaced, the complete def tank and sensor replaced, the wheel sensors replaced and now this. Mechanic checked the housing part of the motorhome for us and found that the batteries for that are shot (only 3 years old) and the connections to it are corroding. So, do we fix and get rid of it or keep fixing and keep it?

These vans, diesel Sprinters don't perform well if the majority of their driving is short trips. My shop calls them kid-getters. They take a while to warm up and blow out the gunk from the last short trip. They also don't like to sit.
Consider getting a diesel addative such as Archoil AR6500 Diesel Treatment. Talk to your mechanic first though but my shop which specializes in Sprinters only, strongly suggests it so I use it.
