Keystone Montana for fulltiming??

I am a dietitian and my husband is a nurse. We are traveling, doing contract that are usually 3 months at a time. Right now we stay in air b&b’s usually but it’s so hard packing up and moving that often and it gets very expensive. Our poor pets get so stressed when we keep uprooting them. So, this is why we are going to get the 5th wheel. We have borrowed the in-laws trailer before and got a little idea of what it’s like. Because we have been on the road for about 6 months now we have already down sized considerably and just rent a uhaul when we move. My husband drives an F250 so we know what we can pull. We are a little worried that the Montana may be a little heavy.
