As mentioned by many here it is a personal choice. I have a MH so my dogs can go with me and I have come to enjoy the life style. My pups can stay 6-8 hrs by themselves in the MH but that does not often happen. We are a simple family and enjoy many of the places that our dogs can come with us to. I would think it out carefully and only get a dog if it fits your plans almost always. They need a lot of attention and care if they are expected to be with you in this confined space. They also need to be well trained so they are not a nuisance to others as you travel. There is no need for a barking unruly dog. Just remember that what ever you pay will just be the tip of the ice berg and there will be limitations to what you do and where you go. If those limitations are too much then a dog will only frustrate you.
