New larger TT or not delima

First, we really love our current TT. However, recently ended up with a 2nd large dog (lab) to go with our 6 year old Golden. One large dog in relatively small TT has been fine, but 2nd may prove too much on longer trips (find in in a couple of weeks when we head to Fort Wilderness). Got us started thinking of how we are using TT. We 'camp' much of the time in Nat. Parks/Forest and some state parks. However we basically have stopped going to hotels or renting condos (too many years of business travel have soured me on hotels). Have been thinking of going to a larger Rear Living or Rear Entertainment model. The idea would be using the TT more in place of hotels/condo and not so much 'camping', although we still want to go to the Nat. Parks etc. that we enjoy so much.

Any thoughts on jumping to quite a bit larger TT. Right now, I like the ease of towing, fitting pretty much anywhere and I still feel like I'm camping. In a larger unit I like the idea of large rear window, anytime there's a view, it's out the back where we currently have no windows. Plus, we both have jobs that allow us freedom to travel, but we do work when traveling so the space and separate bedroom is a plus.
