I am trying to decide which make more sense. I make pretty good money and my expenses have dropped dramatically now that my kids are raised and on their own. I could pay off my house and my RV in 2 years +/- $140,000K OR I could put in a kick ass solar power system with battery storage and grid tie. $40K 12V pump system for my well. $3k 1000 gal auxiliary propane tank $5K 8 KW propane back up generator $5K "root cellar" AKA 8' x 16' bunker $10K additional food preps $2K additional "security" preps $5K I already have enough preps for about 18 months except the power preps mentioned above. What do you think?
