Love this skid plate. Ripped off the OEM dirty diaper and had this thing install in little over a half an hour. Would highly recommend this product.

Easy install. I had access to a overhead lift so that helped a lot. The fit was perfect and the product is heavy duty. I would definitely recommend it.

I'm blown away by the quality of these skid plates. Thick aluminum, definitely overkill, but that's what I wanted. Very easy to install as well!

Customer review photo from Ron Moreau

on our 2024 Nova 30C the new L brackets worked great since our Generator does not have the lips. We had to play with it a bit since just mounting the plate to the brackets was against the screw heads on the generator but just barely . so we used one of the other brackets mounted underneath the l Bracker for clearance.. We then mounted it to the following order .bolt,,washer,b,racket,, L bracket, washer and locking nut. We had to also slightly rotate the generator muffler clamp to the pipe to get clearance to mount the skid plate. Your skid plate looks great but we did struggle getting to your recommended torque on tightening the bolts, but I just can't see it ever being a problem. Can't say enough how well your skid plate looks and appears to protect our generator. Let me know if you have any concerns with our installation process.

Great product, excellent protection giving me piece of mind every time I get behind the wheel. Also, Super easy to install and I usually default to handing that task off to someone else. The video tutorial on installation gave me all I needed to do the job myself. Thanks for a superior product!!!

The quality of the study plate far exceeded my expectations. The finish it has also was not what I expected & is far better a than normal powder coating finish. A well worth investment!!
