The windshield wipers on my Class A motor home travel just a little too far on the drivers side. Is this arc adjustable?

as I recall I "fixed" this on one of my vehicles by putting an inch shorter blade on that side.

What @Bumpyroad said. I expect you have blades that are too long.

On older iron, I used to be able to adjust the travel by a couple different methods. I cannot say if this applies to the newer, all sealed, one position, preset at factory hardware.

I have adjusted travel by pulling the wiper arm off the splined shaft, rotating it one spline and putting it back on. It will travel further the other way, usually not an issue. Newer wipers have one only, predetermined location.

Some I have adjusted the linkage itself, the rods that actuate the rotation of the wiper arm, usually hidden in under the cowl and hard to get at. Some have set nuts you can loosen, move a bit and re-tighten to make the linkage rod longer or shorter.

Some really old ones actually had an adjustment set screw on the wiper motor itself where you could decrease or increase the travel.

Have to be careful not to mess up the park position though.

Again, I am old school and don't know if any of these things are built in to newer vehicles, but it is worth checking out.

What Bob said. I have a 1996 MH and have used all three methods to get the blades to cover the area I needed it to clean. At the very least you can adjust it at the splined shaft. Also check inside and make sure the nuts holding the motor in place are tight, mine were loose and caused the wiper blade to not cover the area I wanted.

I have what they call a pantograph wiper system. I couldn't get the setting right until I found the problem was the arms were bending under the hood. I attached some stiff tubing with worm gear clamps. Now the setting stay put and wipers stay on the windshield.

Good luck

Good point.
I had that happen years ago on my 78 Chev pickup.
Wiper coverage was wonky, so I got in there and the bolts holding the motor on were loose, causing it to move around and interfere with the wiper blade travel.
