A FL 70 will do the job for you. But the more important question is: how well can you and your wife get along in the small confines of a truck? If she can drive the truck well that's half the battle, BUT if you and she are used to you going off to work away from each other, there will have to be a major change in both of you to accomodate the new life-style. The change will be more profound than either of you can possably understand, and you will have to be very carefull not to find yourselves having some terrible arguments. Try to talk to some H/W teams and they will tell you, if they are honest, that stress can be hard when you are togeather ALL the time..Godd Luck, but really think this out first. Jim Bunting...
