Having done it for a while, I'd recommend a couple of things for you:
1. Don't buy new for your first trailer or two. Buy used. The trailer will have depreciated to its market value, and the Titan will tow a lot of what's out there. Plus if you're not using it every month, you're not kicking yourself when you look at the thickness of the payment book. Plus, if your first choice or two don't work out to be exactly what you want, it's a lot easier to trade once or twice if you aren't looking at a big chunk of depreciation.
2. Make sure you get a guarantee from the dealer or lot and make SURE you take the trailer out while it's under guarantee. Say you get something that maybe has a water leak from a fitting inside the coach. You get it fixed for free under the warranty. (Yes, this has happened to me.)
3. Look at your needs before you go to the lot. Or go and look around a bit, but don't let them pressure you into buying. Take some time and think about how you personally will use the trailer. For instance, with us, it's important that one of us can sit on the couch and read while the other takes a nap. Couldn't do that with one of our early trailers.
4. Get the right towing gear from the start. Get a good brake controller, and spend the money to get a sway-canceling hitch setup. You can move it from trailer to trailer, and everything you get will tow much easier. Do it right at the beginning and never have to worry about it.
What did we have the best luck with in trailers? Our Skyline (Aljo) trailers were great for us. Our Fleetwood (Prowler and others) were a real PITA. Maybe they make them better now, though. Currently we have an Arctic Fox and just love the thing. It's been with us for eight years, and is solid as a rock. Great construction, really stands up to the beating we give it on back roads; and it still looks great, even after all these years.
Stay away from a used premium trailer like an Airstream that might seem to be a really, really great price. It's that way for a reason. If you're into restoration projects rather than camping, then that's something else.
Hope this helps.
