Wanted some thoughts/opinions on a concern as we work towards purchasing our first hybrid. I have seen some used trailers for sale, some at a great price. My main concern is more than just leaks and such but about pets. I was looking at used to save some money on our purchase but I wonder if it is worth it. My wife is a little nervous since both she and my son have some bad allergies when it comes to pets. She is concerned that the previous owner may have had pets IN the trailer and although my wife and son can be around cats and dogs, it will start to bother them when exposed to pet dander for extended periods of time (which I plan to do in the trailer). I always ask the owner about this but often the seller is not the only owner since new OR its hard to believe them. When I was purchasing my first PUP we asked the seller point bank about pets and he proceeded to say that the dogs never went in the trailer but was then interrupted by his son who said otherwise. Lets say, he was not happy with his kid when we walked away. I wonder if there was a way to "check" for clues about pets in the trailer. Or should I just forget it and go new?
