I think that's a personal choice. You know what your skill level, your patience level, your schedule, or your budget permits. We are fortunate to have a good RV service place nearby, so for some jobs we have used them, but for other things, we have done the work ourselves.

I like to do as much work as possible, but recognize that I may not have all the skills or patience for certain things. 

Some things it depends what you are doing, how old the camper is, and what dealer you are taking it to.  I replaced some wood in my popup roof and repainted it.  I'm sure no dealer would have done what I did.  They would have said buy a whole new roof.

I needed a new HWH for my RV.  I talked with a service dept when I was picking up some other stuff at a dealer.  The guy listened and then he said "what year?  1989.....you should be talking with your sales dept".  They thought my RV was a POS because it was so old.  I had just bought it 6 months earlier.  Needless to say, I now feel that dealership is very snobbyish and I will not even think about going there again.  I have since found an RV repair shop in my town that does great work, talks to me, and I have only good things to say about E.L. Carpenter Repair in Downingtown PA.  EL Carpenter replaced my HWH for $800 while the other dealership quoted me $1,300 when I finally told them I wasn't buying a new RV.

There's a question sometimes that you either DIY or scap-it...because any outsourced work would exceed replacement cost.  :ranger:

Depends on if it warranty work or not ...  I've seen just about every possible thing done to a trailer, even know a guy who along with friends installed electric brakes on his pup in a campground ...

All our friends laugh because I'm always doing some mod or repair when we go camping. I keep all of the necessary tools in one milk crate so I can just throw it in the trailer... And I just got a bigger crate!
More tools = more mods!!!!  ;D

We will see how it goes for DH who is a great mechanic but is recovering from a bit of leg surgery, is 6'4", a bit ( :D) overweight, and needs to take out the TrailManor water pump and install the new one this week. With the hot temp and sitting in full southern exposure sun all day, I sure hope his DIY goes well inside those cramped quarters. We'll have to run two long extension cords down the hill from the house to the street to put in an electric fan!

My DH is all for letting a pro work on something.. in some cases I agree..like my Toyota truck. Have to remove half the engine to be able to work on it.

But in the instance of our popup, we do all the work ourselves.
