Wow, lots to think about.  Yes, I really want to stay with a 250. The truck will be my daily driver for errands and carpools.  Still trying to swallow giving up the SUV. However, I am definitely looking at all the numbers.  It's amazing what truck salesmen don't know.  Having to get a bigger truck is on the negative side of choosing a 5th wheel over trailer.  However, that 5th wheel sure offers more.  Also, I don't plan on going bigger.  This will be our 5th trailer. We have 2 big teenagers now.  Like I mentioned before a really small travel trailer is my first choice but right now I want the double bunks.  Thanks, so much to think about.
