We just picked up a Forest River Wildcat Maxx that is one in their "1/2 ton series". Seems to be pretty well built compared to others in it's price range. Nothing really jumps out as cheap except the furniture which we are eventually going to replace. I nearly bought an Open Range Light. Really nice unit, but didn't care for the cable operated slides.
One thing for sure, I would not want to tow it with a 1/2 ton. At least not one with stock suspension. I think it lists around 8700 unloaded close to 11k loaded.
