Nice set up!! Great power gen portion.
Seals work for me too. I didn't like the leather seals GTE/Sylvania Corp used. But it worked, and still works. Yours, like the AMG, needs to be lubed every once in a while to keep the seals undamaged. And we found, that lowering and raising the mast 2-3 times a week, kept the moisture out of the mast tubes. When you keep it up too long, due to the mast pressure leaking and being recharged, that moisture can build up fast. When the weather freezes, it caused us problems. Often, the moisture ran down the sides or the tube, and then froze. The mast didn't want to come down, and we had seal failures. The seals you can live with. The compressors just runs longer. But should you want to retract the mast, that's interesting. I came up with a way to do it, but it wasn't "approved" by CECOM. Still worked.
What kind of lights are going to put on it? Or use it as an antenna?
