Rule #1, DO NOT buy an enclosed trailer manufactured in GEORGIA! Now having said that, what do you plan on bringing with you to shows besides you car? I have owned around 20 enclosed trailers in the last 35 years and tow for a living. My minimum is 24' for that, but I also have a 32' LQ trailer with a 20' garage and it is adequate for most anything and will work for a Roadrunner. Being that you tow with a 1500 I would consider a 20'-22' but if you plan on taking a grille, lots of chairs, a pop-up tent, and larger coolers then a 24' would be good. Trailers have gone nuts in pricing and you get what you pay for. Aluminum such as ATC, Featherlite, and Rance are the best out there and pricey! Some of the better non-aluminum are Load Trail, H&H, Sure Trac, Stealth, and Vintage/Millenium. There are dozens of brands, so do your homework!
