Priorities?

I've only purchased one, cash, and if I ever do it again my experience will make me look for the leaks first and determine how bad they are.

Other than that, I think your list of priorities are pretty good. A dinette is pretty critical, but sleeping a kid is much easier on the couch than the dinette. The walk-able queen in the back is pretty big deal as well. It's nice to arrive and slide out, but I would not put a slide out on the important list because it's one more thing to break.

1. Size, I need to be able to park it at home without having to pay to store it.
2. A non-slide floorplan based on its size.

I think cost is the #1 priority for everyone, even if they don't admit it.
The type motorhome A, B or C, gas or diesel is probably next. After that size and floor plan.
Condition is very important.

But, for some forum members the #1 priority is, 'the one without a rubber roof.' :)

I would say condition, condition, floor plan, quality, cost, proximity, ...

By far condition is the most important factor, if the paint is peeling, roof leaking, wood rotted, tires worn out, the floor plan and price don't matter.

In buying my current coach the first one I looked at 3 miles from home was a fixer upper (money pit) 1996 Safari Trek 2830, the seller was moving out of the US so was motivated to sell, asking price was $6,900. I said it was a money pit, leaks, nothing worked (generator, roof air conditioner, dash aircondition, refrigerator all broken), tires were old, paint peeling. He was down to $4,500 and make an offer when I walked away. 5 months later after much shopping I ended up buying a 2002 Safari Trek 2830 (exact same floor plan as the nearby '96 Trek), it was over 1,000 miles away and I paid a bit over $20,000 for it, however it was in very good shape, well updated with $10,000 in parts alone added in the last 2 years before I bought it (new fridge, tires, carpet, seating, suspension work, solar panels, inverter, ...)

I don't care what any says, floor plan is usually first !

Price is usually second, but the price CAN trump floorplan.

Third is condition, but usually this is a negative on a used RV. Excellent condition is not going to be over undesirable floor plan or a very high price. But bad condition will kill floor plan and price.

We bought a new 2016 22ft. Thor Class C.
1: New. Used class C's we looked at were close to the price we paid
for our new rig. Also we get a full warranty which is very
valuable to me. Don't care about the depreciation.
2: Size: We wanted a 22 to 24ft RV with no slides. The only one we
could find and afford was this Thor. The floor plan didn't
matter because at this size they are pretty much the same.
3: Quality: After doing research I found this RV is pretty low on
the totem pole in that respect, however if handy with a
wrench, which I am, it should work out. Knock on wood
we haven't had any major trouble.. yet. 38,000 miles
and 3 cross country trips later the E350 Triton V10
chassis has been what I expected, trouble free and
a bit thirsty.

We only buy new. For us, Floor Plan is the most important. Cost is of little importance because if we can't afford it, we don't buy it. We also won't settle for something that isn't exactly what we want. If we have to wait and save up for exactly what we want, that is what we do. That goes for everything we buy, not just a RV purchase.

IMO, the OP appears to be leaning toward a used Class C in the 30' range bought for cash.

With that said, I look at cost, condition, floor plan, build quality, and previous maintenance/repair history all about equally. Any major flaw in the previously mentioned is a DEAL BREAKER.

Most Class C MH's in the above range will offer roughly the same interior amenities so you have to decide if you want slides and jacks in your future. I like the Ford chassis but you have to decide which you prefer. (Ford, Chevrolet, other) You'll have to decide if you prefer going with a dealer or a private party and how far you are willing to travel to do the deal. What you want is out there if you are willing to look for it.

In some cases it might turn on whether you will need a toad and have to leave the rig parked at the campground, or whether you can use the rig itself to run errands into town, etc.

My priorities are how well it fits how I want to use it, something that can change over time. What worked for me 14 years ago does not so well fit my needs now. Cost, new vs used for me are not so relevant, I'll buy only what I can afford or want to pay for, and new could be a better buy. You can get lost in the details, I've known people who got stuck on things like "it has to have at least three slideouts."
