Were coming to FW in December and we figure it's going to be around $1000.00 for round trip from MI. We have a dually F350 and pull a Fifth wheel. We're thinking about getting an auxilary tank so we can fill it up when we see cheaper diesel does anyone else have one of those and do you like them. The one I saw you have to transfer the fuel into your tanks but we thought it would be ok. Also thinking about getting an air intake system from K & N suppose to increase power and fuel has anyone put one of those on their truck just curious. We have been going to the fort for about 13 years now and still plan on coming down. It's our big trip of the year.
