Welcome. A great adventure awaits. Having camped for many years and owned several RV's may I strongly suggest that whatever you purchase prior to purchase take it to a qualified non biast RV service center and have everything checked out. An honest sales person will be fine with this and it will minimize problems later after money has changed hands while there is motivation to fix problems. And most of all have fun with it all.
I went with a 18X27 twelve foot tall canopy from Tri State Canopy. a few years back. total cost including installation was $1,550. I added a wall on one side by screwing galvanized rippled metal to the studs. Heavy winds have not done any damage. Rated for 85 MPH. Go bigger and taller than you think you will ever need .
Not inn favor of it. Lack of respect & manners which is the new normal sadly. However if there is a direct route to the lake through my space and they ask I am fine with that. What really fry's my bacon is loud drunks who do not respect quiet time.
It is fun to make it your own. I have added family pictures mounted behind plexiglass on my fridge door. These pics have a way of turning to solid gold with time. Also have added functional storage for various stuff. My DW says this is tacky. Well yeah but functional. I want tye die curtins. DW says no way.
No reliable monitoring technology I am aware of. Though you have my understanding having ran out of LP twice. Brrr. An automatic switch over is one option but then you may have two empty tanks if you forget.
