There are a lot of good used hybrids out there, but, there are also a lot of not so good used hybrids. If you can find one local, and have it inspected before you buy it, that would be a bonus. I have owned 3 hybrids ..... two which were Kiwis I purchased used, the 3rd is my current StarCraft AR-One which I purchased new. The AR-ONE is the twin to the Jayco Swift. I am a huge Jayco fan, the only manufacturer I will purchase, but I can say, I did have a few with water leak issues. The two kiwis both had water damage ....the first, a 2000 17A had gone back to the factory and had been repaired, the owner had all the paper work to show me.... the second was a Kiwi 25E, it had to have the roof replaced by the dealer, because the AC seal leaked. The main reason for water damage is lack of maintenance. So, in saying that....heres what to look for. Get on a ladder and check the silicone on the roof ....if it is tried up and cracked, it hasn't been maintained. On the Kiwis, inspect the silicone that seals the front and rear walls to the rubber roof .....if they are gonna leak, that's where. You don't have to climb on the roof .... pound it with your fist, if its been leaking, the material under the rubber membrane will get soft, and u'll feel it. it'll feel soft. Also check around the AC unit ... there are 4 mounting bolts on the AC unit that are supposed to be checked and tightened yearly, most don't, and the rubber seal will eventually leak. Next, look inside the storage areas, look at the plywood that is exposed in the storage area, look for traces of wetness. Look at the linoleum, when the plywood floor gets wet, the linoleum will begin to change colors. Pound on the floor, it should be hard as a rock. Now, go inside, step around, feel for anything soft....even look inside the cabinets. Now, look up, look at the ceiling ....any sign of water damage will form dimples .... and check those shelves that are at both ends up top ... look in the corners, if there is a leak at the roof n end walls, the ceiling material will start to dimple and sag. Push up around the A/C, see if the ceiling is soft. Also, as most are fiberglass .... look for delamination or bubbling. When the wood that the fiberglass is bonded to gets wet, the outside panel will begin to pull away.... that's when you have problems. Just take your time when inspecting a used one, if they aren't hiding anything, and it is supposedly in good shape, they will want you to look! Good luck...there are still lots of good ones out there
