Bumper mount bike rack
We have a 2017 coachmen freedom express 236bhs. We recently purchased a hitch adapter so we could use our bike carrier behind the rv. Does anyone else use one? How do you know if the bumper is strong ...

To calculate weight added to, or removed from the tongue, you need the distance from center of axles to tongue, and the distance from bikes to center of axles, and the total weight of the bikes, plus carrier, hitch, etc.
For bikes on rear bumper, calculate this way (numbers used for example)-
Tongue to axles distance = 15'
Axles to bikes distance = 10'
Weight of bikes, etc = 200 lbs
10 / 15 x 200 = 133
133 - 200 = -67
200 - -67 = 267
The bikes will remove 67 lbs from the tongue and add 267 lbs to the trailer axles.
For bikes mounted on front of trailer, use this-
Tongue to axles distance = 15'
Tongue to bikes distance = 2'
Weight of bikes, etc = 200 lbs
2 / 15 x 200 = 27
200 - 27 = 173
The bikes will add 173 lbs to the tongue and 27 lbs to the trailer axles.
