I think most people buy in stages (at least I did). I bought a small TT at first because of my Tow Vehicle. Some people may be able to afford both at once, I think most limit themselves to starting out with a smaller camper and tow it with their current vehicle. Several years later I could afford to get a bigger tow vehicle. Several years after that I could afford a larger camper (that was about 12 years after I bought the first one). I now have what I need and am good. A few years from now I will probably buy another tow vehicle, but it still will only be big enough for my current camper (a 28'), I have no need to go bigger with either one.
