I do agree with getting what you want now instead of starting at a smaller trailer, which will feel very small the first time you're stuck inside when it rains. But it takes a big learning curve to tow a large trailer, this includes getting it set up properly to tow and learning how the effects of winds and being passed by semis feel. This is where starting smaller comes in. You don't need a duallly, but a 3/4-1 ton will be required for the trailer in the original post. Yes a 5th wheel does tow differently than a TT and by it's hitch design lacks the input on the truck a TT does which is what makes them so stable while towing. A proper hitch with a TT will make towing a large TT comfortable. I'm using a Reese Dual Cam and it is set up perfect. This took many trips of hundreds and hundreds of miles to dial in!
So take a step back, do a lot of reading on trucks and different types of trailers to get an idea of what you're going to like!
Good luck on your decision! In the end you will be very happy.
But with a family of 4 or possibly 5 (yes your wife told us a lot! :B) and 3 dogs, a small trailer will get old fast!
