Hey George, to determine if the Kwikee Electric RV Step # LC3747453 will fit your 2018 Thor 35m it will come down to the dimensions of the step compared to what you have on your motorhome.

The overall width of this assembly is 24-3/4", the mounting plate dimensions are 24-1/4" wide x 8-5/8" deep, and the mounting bolt pattern is 22" wide x 6-1/2" deep. I would compare those dimensions to the cutout area for steps on your motorhome. Let me know what you have and if this would work or not.

If the width matches up but the bolt pattern does not you can always use a new set of mounting brackets with the part # LC301704 to make i work as well.
