I am building a 6 td. and have been doing so for quite a while.
When people ask me how its going, my answer is always "I'm Making Progress"
I have all of the major aluminum structure built except for the fuselage.
I am painting those parts one at a time and boy am I getting excited!
There are always challenges, and the more complex mentally or physically they are, the more you feel great having accomplished each one of them.
For me the Tanks were the easiest to understand, how they are assembled and sealed all made sense. I have worked as an A&P and IA, and have repaired many tanks like them, but...... I had not built tanks from just materials, it was a long suffering messy, stinky and sticky process with some time limitations.
When I was done, I waited a few months and pressure tested them knowing that a leak even a small one could mean more goo, rivets and temptation to verbally express myself inappropriately.
I manometer tested each one for 2 full days, they only fluctuated with the temperature change in my Garage-mahal (Big Garage) and had no indication of any flaws.
After the test I had a bigger sense of accomplishment than when I drove the last rivet it the last tank. It felt good knowing that task was fully accomplished.
Build the plane you want to have your RV-Grin photo taken in, even if it ends up looking like a shopping cart, it will be your accomplishment and you can be proud of it!
BTW-With your concern for quality, it will not look like a shopping cart
