Road-trip with my girl

For past three weeks I am trying to locate an online company which provides information about rvs for sale. Thing is I have planned for a road trip with my girlfriend. My girlfriend is on her vacation, she will be free for a month. I wanted to surprise her with my road trip plan. If you have knowledge about any online company which sells RV for a discount price please share the information with me? Also, if you can mail me the company address I would appreciate it big time. I have not informed my girl about the road trip. It wants to be a special one so I have decided to inform her after buys a new RV. If I could not buy a RV I will rent a second hand RV for ten days. It’s been more than a year since I had a vacation, hope I will have a wonderful vacation this year.
