This has been a very worthwhile thread with lots of well thought out opinions.
As one who had gone from a TT/SUV combo our drive to the destination in the crew cab is cramped but doable.
To the OP consider how far you plan to travel on a regular basis.
If your trips are shorter than 3 hours 5'er /crew cab is OK. The tougher drive will be worthwhile once you arrive at your destination. The trailer will have more room than the class A
If your destinations are regularly 3 hours or longer. The easier more comfortable drive favors the class A.
