^Yup very “basic” for those who know what to do and not horrible for those who are some what handy, mechanically inclined, somewhat informed and wholly motivated.
Totally a diy job for someone who fits the above category.
Not so much if you’re like any of the folks I know who possess zero knowledge skill or desire in any of the things that would lend one the ability to do a diy project like this.
What you said IS easy. IF the right conditions are present. Topography was never mentioned. That is one of the first go/no go considerations.
You, me and many others could walk the OP through a diy of this pretty easy I bet. If he provided any tangible information.
