We purchased trailers to rent as a side business. Would not rent our own. That said, we did have friends that were very successful in renting their personal trailer on craigslist (even though their last customer drove the trailer with the awning out, hitting a tree ripping the awning off and then same tree punctured their trailer wall (trailer was subsequently totaled).
I will say that in general, our customers took very good care of our equipment. Most were first timers wanting to try out a popup or travel trailer. Most had very little towing experience. We treated our rentals as if they were our own, they were very well maintained and looked in near new condition when we sold them.
If you are considering renting your own--here are some of the things we experienced that were unsettling to us;
-customer asks if he can use his mom's credit card to pay for the rental on a $15k camper
-customer came to pick up the rental without a hitch receiver (we provided the hitch)
-Customer came to pick up the rental under the influence of who knows what
-Customer turned too soon out of a fuel station getting caught on a cement pylon ripping the back edge of the camper off
-Customers having blow outs on the road (speeding?)
-Customer missing the toilet and soaking the floors/wall
-Damage to the already fragile furniture, stains on cushions
-Scratches, dents interior and exterior
-Roof Damage (hitting tree limbs)
-Bumper torn off
-Blinds ripped off the wall
At the end of the day, we could not make enough money to make it worth the financial liability and stress we experienced.
