Routing of TV cable

Last week we were at a progressive campground that had cable connections at each site and even loaned us 30 ft. of coax at n/c. However, we ran the cable under the door to the TV on the counter top above the refer and kept tripping over it.
So, I have two questions: 1. is there a snappy way to route coax from the outside on the port (drivers) side of the RV inside to the counter top?. I've seen the flat TV cable piece from Camping World but it seems pricey at around $11.
Hope someone has already solved this problem.
2. In your experience would one 25 ft. piece of coax be sufficient for most campsites or would two 25 ft. pieces be better.
