Dropping an RV off for servicing is pretty difficult. I consider RV servicing a gimmick.
When I first got the RV, there was the inspection that identified some things that needed fixing. All relatively minor. I had to bring the RV home and then take it back when the parts came in. Then I had to drop it off and come back to pick it up when it’s done.
I also had some minor things that popped up that I had to take to the shop to identify, they ordered the parts, I dropped it off when the parts came in and picked it up another day.
All that stuff I could have done on my own and have sinner become a YouTUbe certified RV tech form my year and make.
What I couldn’t do was more major stuff like a blowout on a tire that took away the paneling on the side of the RV. I dropped that off for an estimate, and three months later I picked it up when parts came in and the install was done.
I can’t say DIY has saved me money, its created other rabbit holes to go down, like I installed a really decent solar power system, which took a lot of time, but I love it.
I do the work on my own vehicles except for the tow vehicle for the RV. That will go into a shop. The diesel is too much for me to deal with.
