Class A or Bigger Truck?

I've heard a lot of people that went from a FW to a Class A have gone back to the FW. For me, I think a FW gives you more space than a Class A and you don't have to tow a vehicle to drive around while your Class A is set up for camping. I've considered upgrading to a motorhome from a TT, but after going to a lot of RV shows I think if I were to upgrade, I'd go with a FW and pickup truck combo. I do like the idea of being able to utilize the RV while in travel, but for me....i'd be driving either way, so everyone else but me would enjoy those benefits. My problem with a pick up is that I have 3 dogs and even a crew cab isn't enough room for them in the truck.
