If you use the bumper bike rack, just a word of caution . . .
If you use the bumper bike rack, just a word of caution. I tied my bike to the upright and put a wrapped a facecloth around the crossbar. After driving 3 thousand miles, I had my first opportunity to take the bike for a ride. The round ring on the bar, wore through the facecloth and started to rub through the cross bar on the bike. I'll be putting it on a bit differently when we leave.
I have an old towel that I wrap around the crossbars of the bikes right where the bikes are pressed against the upright bar.
I just make sure that the bikes are bungeed so tight that they don't move . . . so far so good!
As for other issues with that rear bumper bike rack . . .
1) Drill more holes and put better screws all around in that black plastic tray . . .
First time we used it stock from the factory all four screws (yes, just four tiny screws) didn't hold and the tray broke out of the bumper (good thing I had those bungees so tight).
2) If you go down a dirt road, be prepared for anything on that bike rack to be completely covered in dirt or mud (been there . . . got the t-shirt).
