Go to Carl's, They Take Care of You
I have a semi pro football team, and I rent from Carl's Van Rentals every time we go out of town. I've been using them for about two years, and I really appreciate their customer service. They really care about how they treat you. It's not like, just sign up and get out, they really put in the extra effort. They want to know if you have questions, they want to make sure the customer is happy.
If you want a nice, clean van, go to Carl's!
