Hi, I'm a GMG DC owner, and a Bull owner.. I want to replace my DC, but the RT-340 is too tall in height for my needs. I'd like to get it under the tonneau cover on my pickup during the winter months here in MN. I'm wondering if there is a minimum height mod on the rt-340 that I can do to run this right on the tailgate of my truck. Can you simply NOT install the legs and get a few inches? There's no stack to shorten, but is there anything on the top/bottom that can be removed or shortened? Thank you!
