BBTX hit the nail on the head - anything mechanical or electrical is always a toss of the dice on whether you'll have issues at some point or another.
Risk versus Reward = Reward is far greater for us that the risk so off we go in the RV
๐ ๐ ๐In 16 years: Hydraulic slides failed once on fifth wheel (bed slide wore hole in the hose stupidly placed under the bed moving back and forth friction over time at build).
Bought MH new 13 years ago - A/C wouldn't work and service hadn't a clue (solved it ourselves thanks to a forum like this = teeny hidden deep switch behind a panel behind another panel), Auto Awning switch same thing service useless to get it resolved, did it through help from folks on a forum like this. Biggie for us was had first several trips with engine dying challenges and eating up of precious vacation time back then, and needing to be towed often, allowed engine to cool and travel at night rather than lose all our vacation time - were accused of putting dirty fuel in a brand new RV and clogging the filters first time and wanted us to pay outside of warranty = we didn't!. Finally someone at a basic Ford auto garage in Milk River Alberta before crossing over US border where we limped to in summer 2003 said "I think it might be a failing fuel pump". Limped over border next day, had assistance from fire dept to get into a car park when stalled at traffic lights in Great Falls Mt. Limped later that night in the cooler weather to repair facility outside South Dakota to next morning tell them what had been going on and suggestion on fuel pump. They replaced the fuel pump (had a mountain of replaced ones in their bay area) and zero problems for 10 years after other than minor sticky jacks, replacing odd wearing of tyres and general maintenance. Then Easter 2013 broke down on I15 90 miles north of Pocatello Idaho where we were towed to. Sounded like hubby had driven over a shopping cart caught underneath = small $2 clip failed inside and rod punctured holes requiring a replacement engine for $7600. Again no problems until we installed full boon docking solar system end last year, and the Midnight controller failed under warranty boiling the brand new batteries just recently.
Were we frustrated in Year 3/4, you betcha, especially when we only had 2 or 3 week vacations tightly planned and a brand new MH kept dying on us in hot weather = saw more repair facilities than attractions. However, today, looking back at all the wonderful memories and experiences we've had over the years, it was worth these now thought of today, minor inconveniences back then.
For sure it does seem that some folks experience more than their fair share of problems all at once sometimes. Could it be they bought a rogue rig or badly maintained used rig, or one not suitable for it's intended type of use or known in the industry for certain issues? A well maintained by the previous owners used Rig, seems to give a lot of second and third owners hassle free travel we've tended to read. Plumbing issues happen in SnB, so provided they are caught quick enough and addressed damage is usually more a little inconvenience than major expense. If not addressed then of course water leaks can cause untold damage. It's a question of checking your rig regularly, knowing how she rolls, and doing routine maintenance as with all things we own.
Ironically we've been put off buying a new DP due to reading of so many folks spending their first 2 years parked at the dealers or manufacturers getting lots of warranty work done, and some often still not resolved after two or three attempts. That plus the front end depreciation hit, and all the new "more to go wrong" items makes us keep putting off replacing our 13 YO gas RV right now, albeit hubby would absolutely love a new Entegra or Tiffin Bus.
If OP is serious about RVing, he won't sweat the small stuff, and give it a shot with careful front end selection of the right rig - misfortune can happen to anyone with anything but it's more an anomaly than a commonality from speaking with many over the years. We say that with not an ounce of mechanical, electrical or technical knowledge - it's been forums like this that have helped us resolve many issues.
That's been our experience but of course YMMV.
