Its interesting that Evergreen took so much time in design to give the Amped a lot of ground clearance with a high quality suspension system only to have the sewer dump hardware hang so low. That's a great idea to raise it up as high as possible. I'm going to do the same to mine. I have not encountered any hang-ups, but I haven't taken mine off road yet either. Also, the black and grey drain valves are quite far under the unit and takes some bending to get at them. It's not that big of a deal as long as the ground around the dumping area is either paved or dry, otherwise it could get a little muddy or messy.
