Well, we started out in a tent. A year and a half ago, we bought a popup. We were driving an Astro at the time and had to worry about weight. So, when we had to buy another vehicle, we decided on what camper we would want next and bought one within that tow capacity. We now drive a Chevy Express 1500LT with the heavy trailering package, tow capacity 6600lb.
In Dec we traded our popup for a hybrid. That is a cross between a regular camper and a popup. The beds pop out of the ends, but most of the trailer is hard walled. We moved up because we wanted a bathroom (too many middle of the night potty breaks) and the kids wanted seperate beds. We bought one with one set of bunk beds and 2 popout bunk end beds. We did not want to go into debt so paid cash for a 2000 model. BAD IDEA!!! Last month we found out that it had water damage that we did not know about.
If you have 2 kids, you want a set of bunk beds just so they have their own space. We made the mistake in our popup of thinking, "they can sleep together on vacation". Well, this one kicks, that one wears pullups to sleep in, the other one stinks, I am not sleeping with her, etc. Not happy campers. Easier if they each have their own space. Also nice because they can go to be while we stay awake.
We are currently dealing with the dealer and manufacturer (design flaw for this year) to get our money back. They have another camper on hold for us that we will be getting after our money is refunded. It has 2 sets of bunk beds, a sofa bed, dinette that can be a bed, bigger bathroom, bigger refrigerator and a queen bed that slides out. It has a GVWR of 6000 and a dry wt of 4800.
Also know that the pictures you see are usually taken with a wide angle lens and campers "may appear bigger than they actually are".
Be wary of salesman who tell you "you don't need to worry about the GVWR, you aren't ever going to put that much stuff in it." You must worry about GVWR. You not only have to worry about the stuff you will load in your camper, but in your tow vehicle as well. Your luggage, your kids, etc. You need a cushion. If you push your limits, you can damage your transmission over time as well as be a danger on the road. Even if you can pull it, it may cause problems over time. My Astro could pull the new camper, but it would not be a good idea. Stay well within your limits.
Also look into hitches. A good weight distributing sway control hitch will make a huge difference. I would not want to tow w/o one.
A good website is
www.disneycampers.com . Scott has a section called RV101 that has all the basics. I also have the gorving.com dvd. It is great.
