While I agree that some B+ have fewer places for leaks you still have to inspect and recaulk all the through roof items like vents, AC, stand pipes and if you have a slide that will need attention as well.
I have a 24' class C with a 158" WB I also have a Dodge 1500 Quad Cab pickup with a 160" WB. The RV is 2.5 ft longer overall than the pickup but I can and have turned the RV around on a residential street with a standard 3 point turn with no more time or trouble than the pickup but you absolutely must have a backup camera on the RV, the mirrors wont cut it.
I always like to travel with my telescope and mount and fishing equipment, I dont think I could have made the longer trips without the cab over bunk. If you have delicate or bulky items that are not real heavy the bunk is a life saver. I stash the telescope and electronics as well as fly rods and tieing equipment and the heavy coats up there. They would fit in the storage compartment but I worry about them bouncing around and dont want things piled on top of them.
