Hi Pam! We're full time in a 2552. Bought new almost 6 years ago. Close to 3 years full time in that time frame with lots of long and short trips during our grounding (family issues - never again). We have just under 40,000 miles on her. We went through the evil RV break-in time where you find RV component manufacturers knowingly put out some faulty products and you get to fight with them to fix under warranty (not Phoenix - Atwood, Dometic, Onan and so on).
No problems on the build. She's still solid. Any little damage was done by us. We aren't fix-it people but we do basic maintenance. Our one repair task is the house door latch recently got flaky. I bought a new keyless one and may have to hire someone to install if it requires too much modification. I knew it wasn't an exact replacement when I bought but didn't want the same lock. The old lock lasted for years so I can't complain.
The newer Phoenix Cruisers are getting better interior cabinet door latches so you shouldn't have to deal with those breaking all the time. Even so, we carry spares and can swap one out in minutes so it isn't a big deal.
We use everything! Shower, stove top, microwave, inverter, toilet (use it just like the one at home), awning, TV/sound system and so on. One item we haven't used much is the outdoor shower but we just tested our little solar suitcase and expect to be doing a whole lot more camping off the grid so that shower will help with grey water management.
We've talked to people in the campgrounds that say they have to repair something every other month or so but that's just the way RVs are. Not so with the Phoenix... Which is good because we can't fix most things.
