I have the 184BH. We are currently looking at a larger one to trade up to. If I recall, the only difference in what we have and what you have is basically the bunks are switched to a two person dinette, but that the shell is the same. It's very easy to tow, easy in and out anywhere with your truck. I have a Silverado and we've been to Maine and back in ours. No problems whatsoever. The main reason were trading is because we have a growing family and there's just not enough space on a rainy day. The a/c does struggle when it's humid, like it usually is in South Georgia. When we've been to the beach and the air is a little dryer it's okay. I think they have an upgrade to a 13k btu roof unit, so definitely get that if you're buying new.
I think this size is great for two people, but any more and it might be tough when you have to stay inside. Especially since you'll have a dedicated dinette - we use ours as the adult bed. There's actually a surprising amount of storage space in these, so that won't be a problem.
PM me if you'd like any more insight. Be glad to elaborate further on anything.
