How used is too used?

To me, the biggest thing to pay attention to is your nose.

Water intrusion is what kills most RVs. If you walk into an RV and it smells like musty or moldy, leave. If you see evidence of water damage, it will always be more extensive than what you can see. Look for delamination. Push the walls up near the ceiling and feel for solidness, not mushiness or crunchiness. Look at all the places where plumbing is accessible and look for evidence of leaks.

Basically if it smells, looks, or feels like rot, walk away.

If you buy from an owner that has always had the rig under a cover, that's a bonus. If he cares enough to spend thousands on a cover, he'll usually maintain everything else.

I’m early into my research, but I’ve come to that conclusion as well. I’ve got 12 year old twin boys, so 2 sleeping areas with a bunk over cab and a rear bed would be ideal. Comfortable seating during travel is also important to me. I want to keep it under 30’.

So far, these are my favorite floor plans.

Fridges, roof A/C units, furnaces, water heaters, RV generators, fresh water pumps, dash A/C units, converter/chargers and house batteries that are over ten years old may need repairs or replacement now or later. So, if you buy a 5 year old rig, and are lucky, you may not need repairs or replacements for some time. Our 2004 Tioga has had major items replaced, ask to see paperwork. Set aside some bucks for repairs/replacements as needed. The drive train may not need major repairs but good to have a pro truck mechanic check it over.

I agree with most of the comments already stated. One issue that hasn't been brought up is your assessment of the seller and how he presents himself. Does he care much about little details of the rv like stains on the carpet, is there cooked on food and crumbs on the stove? What does his house, garage and other vehicles look like? Does he have pets that he takes with him in the rv? You may not care about the pet issue but I do because I'm allergic to pet dander and have a very keen sense of smell. I'll sum it all up by saying you would never have to worry about buying any rv from me no matter how old nor how many miles it has on the speedometer. I take care of my vehicles because I don't ever want to be stranded on the side of the road if I can help it at all.

We did that last year from a 5er to a Class C. Big thing is having wheels once you get to your camping spot. Easy for us, just drive the C over to wherever and back. Some folks need a car to tow. Another way if the camping spot is not too far away, is for one of you to drive the car and the other to drive the C to the camping spot.

The actual OP question depends on too many factors, but IMO the main one is how good you are on DIY. And DIY on what?

Eg, I am good with the RV stuff, but not on the truck type things. So I mostly didn't care about the "house" side, since I can fix all that myself mostly, but if the truck part is no good, I am helpless. That means also, I cannot tell if it any good before buying it unless I can get it to a garage I trust and get an estimate.

Generally, I agree with the above advice, if you have X dollars to spend, get a cheap RV and use the rest of the money to get it into shape. For sure, since every RV needs some work, if you blow it all on intitial cost, you will have to borrow more to get it into shape.

We are very pleased with our new to us 1991 we got last year :) It is a better floor plan etc than many new ones we have seen.

I agree about leaks! We had some, but Eternabond is your friend at $100 a roll. Not that big of a deal if you are handy.

The way I look at it is a new or newer low mileage unit can have as many or more problems then a well used one. I would rather buy a older unit in good shape that is cheaper and put in my money to fix things that need fixing if anything, then to buy new or newer and spend a ton and still have issues. My 19G was affordable, I did some servicing and it is as good as you can get it - in some ways better than if it was new as I upgraded items to my specs.

Biggest thing is a good body and camper shell.

All good replies. One other very important thing: Previous major accident, flood, or fire damage.

Most motorhome manufacturers only get one chance to get it right. That occurs in the factory when it is initially assembled. (today that can be beyond the scope of many manufacturers) Combining that with major catastrophic repairs done on a shoestring budget (or trying to make a buck) can compound the issue exponentially. Don't get caught holding someone else's bag!

What I need to start digging into now are the brands I can trust, or more importantly, those I should stay away from.

Delivery trucks, shuttle busses, and other commercial vehicles built on the same chassis as motorhomes often go for hundreds of thousands of miles. Mileage (or lack thereof) in itself would not be a primary concern for me. I do think that, all other things being equal, lower mileage means less wear and tear on the drivetrain etc. and would be slightly preferred, but should not be the biggest concern. There are some chassis parts that tend to need repair or replacement due to age, more or less regardless of mileage; there's a good chance that fifteen year old brake calipers may need rebuilding or replacement, for instance. Some seals and belts and hoses and bushings and such also deteriorate with age.

I would avoid units that are old enough to not have fuel injected engines.

Like wrvpo said, check the house and house systems carefully. That's where you'll more likely have work to do and more maintenance to keep up with. A 2012 unit with 10K miles could be in great shape, or could be subject to lots of deferred maintenance. A 2012 with 60K miles could be very well maintained or beat up. (At least with 60K miles the tires would hopefully have been replaced once and have at least a couple more years left in them.)
