yWhen I down sized to a small TC,I kept my speed on the hiway the same 65,was curious to see if others did the same. seems Im passed a lot,but mostly by 5th wheels and MH.
I stick to about 58 or 5 under the limit, whichever is slower...better fuel economy. :)
If the speed limit on a 2-lane is more than 65 (I rarely see 2-lane roads at that speed or above), I will keep an eye out behind me with the side views and if there are more than a couple cars back there, I'll look for a spot to pull off and let them by (signalling, of course).
