No offense meant, but what you’re considering is not a sound plan. Period.
Especially if you are planning on moochdocking. RV parks ain’t open in AK in the winter.
After living up there as you have, your consideration for this seems about as big a departure from sound reasoning and judgement that I can think of.
Someone will come by here and tell you (and me) how it actually is possible. Well of course it is. It’s not truly 100% impossible. But it’s a very very poor decision.
PS if you’re asking, open ended, what you would need to do to “beef it up” you’re already starting out way behind the 8 ball with respect to your knowledge and ability to even think about making it as that small fraction of 1% that may actually pull it off (at considerable expense and even more considerable effort).
