Generic questions about 5-ers

I can say the truck is more important that the FW, so I will likely lean more towards the truck I need for use every day and buy a FW that can be towed with it than vice versa. If I were full timing maybe the other way around. But I have no other use for a dually. This trip next year is a US tour approx 3-6 mos. After that we will probably make extended trips, but there will be large gaps in our travel. I can't justify buying more truck than I need. If that means a smaller/lighter FW, so be it. If we decide to sell the S&B and start full timing after next year, I would opt for a 40-45' DP or a larger FW and possibly a dually. But a truck and camper that big just makes no sense right now.
