Most teardrop campers weigh in at between 1,285 lbs to 1,800 lbs so just about any car or pickup can pull a tear drop camper without a problem.
Some teardrop trailers can weigh as little as 850 lbs which makes them a great option for people who drive small cars or pickups and even a lawn tractor could pull a tear drop camper with ease.
So if you need only a little space and have a small car or truck then a tear drop camper would be a good option.
I've even seen a three wheel motorcycle pulling a tear drop trailer behind it so that's another option.
