A final thought about seeking opinions about what to buy.
"I can never tell someone else what they should do, but I can always explain the choice I made based upon my own use".
For example, we use a SRW gasser because:
1. My wife absolutely hated the dually given parking and driving in heavy traffic such as when we winter near Naples, FL.
2. Our Northstar camper wet weighs 3,500 pounds, well within the capacity of a single rear wheel.
3. We like the reduced maintenance costs of gas and the cost of lower mileage for us is simply not a factor.
4. We are on the road for 3-4 months at a time, but not constantly and the camper can not stay on the truck as we use it for day-to-day chores.
The list goes on, but you get the idea. Everyone has their own list of what is important and less important and it may not be rational given we are all human!
I think the closer the OP's planned usage is to someone's posting, the more valuable their input. My posts may not have much value because the OP is planning a different pattern of usage along with other factors. Others may be in the same boat.
Again no right or wrong, but some sort of "best fit rule" for the OP's truck and camper combo may apply. :)
