Just got 2 sets of these but have not had a chance to use them yet.
Our trailer is a 2109S and there is 2.5" between the tires.
I had to trim 2" off one of the Andersons in order to barely get it to fit between the tires.
I cut off the tip end, as recommended by Anderson. I didn't see how cutting anything off the other end was going to be of any benefit.
I did a 45 deg cut using my table saw.
This will give one tire a steeper ramp than the other.
We will see how it works out in a few days when we start our maiden voyage with our new camper up to the Olympic Peninsula.
