Conor, yes, as long as the bicycle is in good working condition, you pull a trailer, and pack as light as possible, that bicycle should be able to make it across the country like you’;ve planned. But you need to make sure the bike works well. Pulling a trailer reduces a lot of the frame stress caused by loaded bicycle touring, so a trailer is definitely a good idea. Just pack light and only carry what you need. Be safe and have fun!
