Rolling Tarps are they a good idea

Good Evening eveyone,
I got a call from some company I believe they were from Arizona maybe, or Vegas, anyway they called a couple times, I guess since my biz is still pretty new they somehow located me. So he begins to tell me that his company manf and provides trucking companies all over the country with these rolling tarps. I know what they are I have seen them on some trucks before. I said well sir I don't have a 53 foot trailer so I don't know if putting one on a 20 foot would work and so on and on he finally said he was gonna do some research and call me back. I'm just wondering if they are any good and has anyone used them before? what is the reliability of one and how much of a challenge is it to open and close these tarps.

Thanks for reading have a good night

 

I didn't think so either. I looked at my trailer and could not figure out how it would work. I do wish they had a way to cover cars like adjustable universal fit tarps that worked on the highways and wont let a gust of wind push up on it

 

I actually thought about that because my trailer yard is located in another biz that rents u-hauls and they have a ton of them but will they hold on to the car is my question
