Leo,
Not really an advantage for trucks that have big tanks like yours.. for those who can't buy 50-100 gallons at a time, it's a big plus.
The big difference is... you can get a shower with 50 gallons OR 20 (or 25 I forget)gallons, and 10.00 in restaurant in a 24 HOUR period.
This will be good for us vans, sprinters and some small C Units that don't have big tanks.
Up til now, (except for Flying J) we've had to pay for every shower, with no other option.
It's nice to see a company finally recognize that there are a lot of van drivers using their facility.
