I just returned from a week long trip to the Smokey Mountains. Every day I kept wishing I had a cooler to store beer, water, ect. In the past, I have used a soft cooler bag and used a bungee cord to secure it to my luggage rack. Didn't work so well with having to unsecure the bag every time I want to get into it and the soft cooler only holds ice for a few hours on a hot day. I have a trailer hitch and have looked at receiver cooler racks. My concern with them is that it looks like the cooler will cover the exhaust and quite possibly hide my turn/brake signals. What other options are out there? Any advise for this thirsty traveler?
