Since it's your first trailer, do alot of soul searching about how you're really gonna use it and be honest with yourself about how often you're really going to be able to use it. 99% of RVs spend their life in the driveway or storage facility because people have to work, and when the weekend rolls around, there's always something to catch up on. Mine sat in my driveway for the last (3) years untouched because life often got in the way, plus somewhat of a changing lifestyle...motorcycles.
Things to think about:
What is your tow vehicle
How often will you use it, maybe an occasional weekend and 1-2 weeks over the summer
What outdoor activities do you participate in that will complement having a RV, and what will compete with it
How far will you travel. Will you be staying local or alot of cross country trips? Gas gets expensive
Will it be something you sleep in primarily, or someplace that you park and don't want to leave the confines of the trailer
Will you be primarily staying in campgrounds that have facilities (shower, bathrooms, electric) or more boondocking where you're on your own
Alot of questions to think about. Most people buy their 1st camper only to become quickly aware of what they actually needed instead of what they thought they wanted. Also, alot of times, you might not really know what features are important until you get out a couple of times and either don't have it with you, or never actually use it. We did that, so that's why were in the market again
