All excellent advice everyone. Thank you much for the breakout Lava!! I've had 4 boats myself and am very familiar with the Bring On Another Thousand (BOAT) toys we spend our money on :) I feel your pain.
I intentionally left the Cessna 310 off of the list based on what I was researching.....I was finding the fuel burn runs between 25-29 gph, compared to 17-24 gph on the others, but maybe I need to revisit it as an option based on everyone's suggestions.
I've got a Fixed & Variable Cost budget sheet that I was working on as well, but it looks like I might need to update some numbers. I was finding annuals between $500-1000, but like you mentioned that might have been owner assisted pricing.....
Thanks again to everyone who has commented!!
