About twice as big as you think you need! From experience, I went from a 5x8 in the 80's, to a single axle 6x10 in the 90's and early 00's, to our present 6 x 12 dual axle and we already need more room for our Canada Trip. Trust me, get as large as you think your vehicle and pocketbook will handle.....you'll fill it up.
