For us, it was a question of buying a small trailer or a big car, which we didn't want.
My wife was so un-fond of tent camping that we hadn't been out together for several years. I was trying to add comfort with thicker Thermarests and larger tents, but there was a problem with that strategy. All those soft goods were filling up our car, even with a large car-top cargo box. I reached the point where it was looking like we needed a larger car than our compact SUV. However, we would have used that extra capacity only a few times of the year- the rest of the time, we'd be stick with a thirsty, oversized vehicle to park and feed (like 75% of other US motorists, IMHO). Instead, we bought a Scamp
. Now, we can carry all the pillows and comforts we desire (as long as they're not heavyweight), and we can still maintain a FFAFE (Family Fleet Average Fuel Efficiency) of 30 mpg, between our two cars. Sort of a win-win situation, don't you think?
