Wow, that is nice. Do I see a slot floor drain? Do you wash daily or monthly? Does washing inside cause problems? It sort of looks like the RV is in a separate stall.
Very nice.
Thank you!
Yep that is a 48 foot Trench Drain perpendicular to the Door (see drawing below).
Haven't had any problems washing vehicles inside in the 30+ years I have been doing it. Every shop I have been in I had a Wash bay. In my Upper and Lower Garages I have wash bays that double as parking stalls. I mostly use the Lower Garage since it has poured walls, not sheet rock like the upper Garage.
This is the first shop I have had with a 48 foot drain however. So when it came time to wash either the Race Car Transporter at 81 feet OAL or the Motorhome I had to pull them outside. The sun in the eyes and the sun baking the water dry was a bigger pain than wet walls. One of the best things I did with the latest design (final design).
The RV sits in the "Cold Storage Area"...only heated to 55° in the winter.
I only was my vehicles when they get dirty. I use to wash everything daily/weekly when I was a younger man and I could go 2-3 days without sleep...LOL...
