Being new to the RV world some of the things that make it more enjoyable are being able to work on things, diagnose problems, doing ongoing maintenance etc. I got broke in a long time ago thinking along the same lines as you except I wasn't thinking I wanted a company to "step up" and fix anything.
Bought 3-4 year old Jayco pop up from my parents. Dad said everything had been maintained so I didn't follow through on checking things out as I later learned to do. Took the trailer into the mountains about 5 hours away. About 35-40 minutes from our destination I stopped in front of an old store (late at night) and what appeared to be smoke coming from one side of the trailer. Decided it was steam or something from some puddled I had ran through so drove the last twisty curvy miles. On an old mountain back trail, about 1/2 mile from the campsite I was heading to the pop up just dropped to the ground on one side an in the rear view mirror I saw a tire/wheel just rolling over into a gully. Great. The bearings on that wheel were shot and they seized cutting the spindle right off the end of the axle. Had very few tools but managed to prop the trailer up on the four little screw jacks I had and drop the axle in the middle of the night (Sat.) after DS ran down the road waking folks and borrowing some tools. Spent all day Sunday down the mountain in town and good folks were kind enough to come out and repair the axle with a new spindle, bearings etc. Got it all put together in time to go to bed then head home the next morning. THAT was my initiation into having a travel trailer and I've never forgotten it - my truck campers just never had that kind of problem LOL. I didn't blame my dad, Jayco or anything/anyone else - I should have taken the time to inspect the trailer and ascertain it was in good shape - I didn't and that was on me.
Owning an RV requires a certain mindset; one that acknowledges there are going to be things come loose, break or fall off - it is inevitable. Maintenance is something that is required. To some all of that is enjoyable and once familiar with it the routine will minimize any failures. Doing the work yourself adds satisfaction to the process unless you don't like to do it. Taking it to a dealer for all the routing maintenance means you do without the trailer for lengthy periods and spend lots of money. For some it's just not worth it.
Loose screws, staples, brads etc. are part of the game and why I carry an air compressor, brad nailer and stapler along with a ton of other stuff. Once it is accepted that the repairs belong to you and your head can get cleared of that the process of fixing the things that are broken can begin and this forum, google etc. can help you get it done.
