Here's my solution:
based on 2" hitch mount....this slides in, locks in place and allows me to pivot it..i set it horizontal to install milmast pieces, connect antennas, j pole, yagi and hf di pole, feedline, walk it up to vertical, pin in place and guy it if need be based on height....
i can use the back on my suv, of the side mount on utility trailer...
this is a total one man operation....easy peasy...
