Well-I have a REALLY old Valley-I think it is a 1992 or something. I LOVE it. Hubby wants me to replace it, but I am not so inclined. I love the weight of it. I only ever take one horse in it, as the rest is used for my extra stuff-and I will tell you it tows beautifully. I maintain it impeccably, but it has always been kept outside.....still incredibly solid according to my trailer guy who always offers to buy it. I have had it rewired, but other that that-it is not the most beautiful thing, but remains solid as a rock. Valleys are well built, and as far as value-my trailer guy has offered me $4k on trade in (he deals only in Jamcos, which I LOVE, but are super pricey). Mine is a extra wide, extra tall 2h straight load, ramp, double axle, sway bars are a must, and hubby built in custom cabinets in the front for storage...makes it sort of a modified dressing room type thing. I bet you could get one in your price range. I will say that in looking myself, one thing I like about mine that I cannot find is that the divider goes all the way to the floor. I like it because of the fact that I only take one horse, and always have lots of stuff on the off side. I don't want to have to worry about all the "stuff" getting over with the horse. JMHO.
My best friend has an Exiss, which ic a nice trailer-also a 2h straight load, but aluminum......neither one of us likes the way it tows compared to my steel. But, it is prettier, and much easier to keep clean-just hose it out. It has a seperate tack room, so her "stuff" is away from the horses.
