Hi Iamiam and welcome to JOF! Good call for a close by trip, some recommend (me included) to do a camp driveway first if you can. That way you can quickly run into the house if you forgot something. A notebook is a great first step so that you can jot down things that you forgot, things to remember and maybe even items that you took that you didn't need. No matter what, have fun. Making do with what you have is one of the joys of camping (at least in my book). Everyone is very helpful on the forum, so if you run into problems or have questions, feel free to post and ask. Remember we were all new once.
One thing that is helpful is to add your TT/TV info to your signature, so when asking questions we know what model TT you have.
