To the OP - there is some good advice on this tread. The ones you need to pay attention to go regardless of trailer. Get a trailer that is not too much trailer for your truck. If a fully loaded (full tank) trailer is under your weight limits, then go for it. There are plenty of small 5th wheels that can be towed by a 1/2 ton truck. Not all the 1/2 ton towable models meet the actual requirements, but some do. Just get your actual truck specs and start shopping - remember, brochures and websites under size everything or don't show the whole picture. You need to look at real world weights and weight limits.
