Most likely the motel owner is a room or 2 from going broke and may need the extra few bucks from the school bus, or exchange for work.
I can understand it looking tacky, and make one wonder.
If it were a $150.000 rig parked there likely nobody would notice.
I have an older rv.
We at times get looks from the cardboard people in the big $ coaches lol
Reminds me of an RV park we once pulled into late at night.
Was not til morning did we recognize many rv's sported shanty wooden porches and covered under a couple of generations of tarping.
