maybe, I keep a bunch of old armaflex insulaion for things like this. I had to tighten screws on vibration mounts once on mine. Front of pump was touching floor. Mine is 24.1 with pump by tank under passenger side bed.
I don't have an Axis but I did install the kit, I also added a Shurflo accumulator tank. Pump is quieter and tank reduces water pulsation. This is the fourth coach I have added the kit and tank to, I believe it makes a difference.
