Hey Maddog, since you are free to travel now, head for level ground. It will be easier on your truck than pulling hills or mountains and safer. #2 Get a sway bar so your trailer will be less likely to jackknife going down hill and go slow down hill and don't break quickly to avoid jackknifing. #3 Keep all truck fluids checked and changed as the truck will have a heavier demand. #4,look into working at campgrounds to off set rent etc. Google - work for RVers and Campers on the road - to find your specific needs. Lastly and most important as far as small space - you got married to be together - have fun and make it an adventure.
