I've adopted most of my buddies over the years. sometimes from a breed rescue, sometimes from the county animal shelter, and some just from a friend of a friend. The friend of a friend was obviously the cheapest and easiest. I did have a home visit from a malamute rescue, but they have good reason too. Malamutes and huskies are not for everyone, and they don't want to place a dog with someone who doesn't know what they are getting into, and ends up returning it. That is traumatic for all concerned including the dog. That said, I don't think living mobile would have been an issue, as a malamute needs much more exercise than a fenced yard can provide anyway. Sometimes a person may have to explain what their living situation really looks like to someone who doesn't understand, but most will probably not just say no because your mobile. Shoot, if they really knew they would realize that most van dwelling dogs get way more attention and exercise than the average family dog that gets left at home all day every day.
