The RDS gravity feed aux tank is in the 4th truck. On the road I don't always unhook on overnight stops and can get 2 days travel before needing fuel. My last trip I filled at T/A as with the EFS card it was $o.48 less than locally. The 64 gallon was a $30 savings. A long bed with a 48 gallon tank helps the not need a huge aux.
