My only comment is that they are very limited off road,long with little clearance,solid suspension.Depends on your wants and needs.I would expect some problems at that age.
Make sure tractor is ready,waiting until Nov.to purchase "winter fuel".Have a FEL mounted plow for it and a plow for the ATV.Fuel oil and propane tank are full.
$1500-$2500 ,my 10"x12' was $1400 with an opener three years ago,uninsulated.Way better than a "slider".Have a remote on the tractor and side by side.Not a roll up but regular overhead door.
I have a Eufy system,wifi and goes to my phone.Limited to wifi range,solar powered.It works well.No additional cost.
My game cameras are Reveal,cell system.About $100 per year per camera for unlimited.
Owned ATV's/SS since 1981,Honda,Suzuki,Kawasaki and Yamaha.Had the Kawasaki for 23 years and sold it for 1/3 of what I paid.Currenty have a 2021 Yamaha Kodiak and a 2016 Viking.Purchased 4 new Yamaha's.
I had a very similar unit in my garage for 20+years.the heat exchanger finally burned out.That one is 150k BTU,should be big enough.
Mine had a standing pilot.New one has an ignitor.
I spanned two trusesses with 2x4 and used all thread rod to hang.That is a bigger unit,you may want to...
My SIL just purchased a 2025 GMC AT4 with the 6.2 V8(I told him about the problems) because his 2020 5.3 failed!
Supposed to be fixed with the 2025,I hope so.
I used to trade every two years,not any more.
I have had gamebirds for about 35 years,pheasant,quail and chukars,started a preserve 22 years ago.We are in New York state near the Canadian border.Going to miss all the people and dogs and friends we have made over the years.
Never was a money making proposition more of a keep...
