Traveling with your Fur Kids is easy. Just get an extended or crew cab TV. We removed the rear set in our TV and have a large UltraLite Cage mounted in the space. We travel with 4 Cats and they travel in style and are just a comfortable as we are.
We went from a 34' 2 slide 5er to a 41' 3 slide 5er because after a few months the 34'er just became too small.
If your Hubby is used to Semi's it's easy to fill up a large TV/RV combo using the same truck stops. We try and plan our fuel stops based on truck stop availability.
