Stock tank would be easiest especially if you have to move the old tank before setting the new one. I'm not surprised by RSs refusal to assist. I have a 300 still under warranty currently failing that they refuse to replace. They told me to monitor the seams and check back if it gets all the way past the seam protector amd onto the actual seam. Feels like they just want to wait and hope the warranty has expired before it actually starts leaking.
For anyone considering a RS tank.
