Gotta say, the inside cleaned up a lot better than I'd feared.
the bathroom and stove were the worst. The stove had candle wax all over it and took some elbow grease. Took a hose to the bathroom.
Cushions in back are toast from sun and water damage.
Roof needs some sealing.
But still looking like it will be worth more than $400 (Usual bike sale price here)
Still a win!
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
