For the most part,big rigs have tow diesel tanks,one on each side My truck holds a total of 240 gallons Do you remember the name of the truck stop that was on that show? Or the town it is located in? If it's the one I am thinking of,it is in Walcott,IA It is a huge place
I have been there,but it has been awhile Usually the only trucks stops that don't have showers are the real small ones I am working on a model now I plan on eating around 4:30 this afternoon
