My wife and I have had a small fold down travel trailer for years and have been wanting to upgrade to a hard side trailer. We have been researching via the internet and otherwise for quite some time, and have made a down payment on an Escape 19. I have been following the forum as it is a wonderful information source. I appreciate everyone's willingness to share information. I've been wondering about a wheel on the tongue jack. This seems like it could help provide some wiggle room when hooking up, but it doesn't seem like most people buy this option. What are the pros and cons?
