Have you not looked at the tent trailers? I only say this to save you the $$$ and to make sure you really can afford the time to camp a lot. How many nights a year do you know for sure you'll be camping? Your Suburban could tow a larger tent trailer...
Before we bought our current setup we bought a used tent trailer for $2K and used it for three summers while we dreamed, shopped, looked, etc...then sold it for $2K.
Just for people in general I always mention going cheap to make sure you really like it and too, that you have the time to really use the truck/trailer that your going to break the bank on.
Craigslist is full of ads of barely used Campers, TT, etc...that barely got used.
