I suggest looking at a few and think about how you will live in it. Move around like you were living in it. Pretend to watch TV, fix a meal, and sit on the toilet. Stand in the shower and move like you are bathing. You get the idea. Some places will just let you look and wander on your own. Picture where you will put your stuff. We too travel with a 2 year old and quickly realized she needed her own room so we could have adult time. We have a bath and a half with a separate door to the outside so the grand babies don't have to walk through the trailer to use the bathroom. Only you will know how and what you will use it for. Make a list of what you want and don't want. We also had health issues to account for and needed a unit that would accommodate those needs. There are a lot of pretty trailers out there. Find the unit that fits how you live and that will be the right trailer for you.
