Funny how a service writer or some other person tells you it's "normal" and when you call them on it and explain you called the manufacturer, they change their tune.
Took the 20MRB back to the dealer to have a few tweeks done under warranty. I mentioned here, that on our 5400 mile trilp, the main fuse on the battery blew whenever the slide was brought in just using battery power with no shore power. The service manager said this was normal. I said, that cannot be because I know that if you are boondocking, you are going to use battery power to move the slide in or out and the fuse should not blow..
He went on to say that when my fuse blew, it was due to the batteries being low and sucking so much power to close the slide. I mentioned to him that this happened two hours after leaving the campground after being hooked to shore power for 12 hours. He then re-thought about the situation and says "it is not normal".
To make a point, after he had the slide out and brought it back in, I went to unhitch the TT from the TV but the tongue jack wouldn't work. I pointed that out and he had a tech get a box of 30 amp fuses.
Hope he finds the problem.
