Do You Have Running Boards for a 2020 Thor Quantum 25 Motorhome?

Question:
I need a running board or cab step for a 2020 Thor Quantum 25 motorhome on a MB Sprinter. Do you sell something, or perhaps a universal that I could modify to fit?

Hey Bob! I am sorry we do not have any custom fit running boards or steps for your 2020 Thor Quantum 25 Motorhome. Additionally, I checked with all of our vendors and none of them make a set either.
The only universal option I have that might work is the DeeZee Universal Nerf Bars item # DZ3700301. The main issue is they are 32" long. Looking at pics of your motorhome, I am not sure there's enough space between your front wheel wheel and past the door where the Thor body pushes out from the Sprinter chassis.

Hey Bob, did you get a chance to see if the DeeZee universal nerf bars would fit your Thor Quantum on the Sprinter chassis? Your update could make it easier for others working with the same setup.
