I'd agree with the first two posts.
We were left out in the cold one time when the camp ground only had 50amp hook-ups avaliable and we didnt have a 30 to 50 adapter and no RV stores in the area had any either.
Here are a few things I'd Make sure you have
- Good water Regulator
- Fresh water hose - 20' length should do you fine
- Water Filter from outside spigot to Camper Inlet
- 20' minimum of Sewer hose with a clear elbow to know when your tanks are clean and another elbow for the sewer head in the ground
- If the temps are going to get chilly at night, bring a small ceramic heater so you wont waste all your propane - But make sure you're hooked up to shore power before you run it - we found this out the hard way
- Light weight ladder - You might never need it, but you'll be glad you have it when the time comes around.
- Small Shovel - Various pieces of wood for leveling TT - Good length of Rope and a few carabiners for attaching things around the campsite
- Good comfortable Camp Chairs for relaxing around the campfire
- Wet wipes, for cleaning off and not having to waste water
- Awning Mat - At first we thought we wouldnt need this, then after sweeping out the floor 5 times a day, we found out it was indespensable. There have been a few times we camped and the ground was muddy or the grass was nasty and this made all the difference
- We bought a good fold-up table from Camping World, but so far, every campground we've stayed at has multiple picnic tables, so we've never even taken it out of the box? I guess it just depends where you're going to camp
- If you're going to be boondocking, a good generator, or solar panels to keep your batteries charged
- Thetford Black Tank Deodorizers - Just drop one in with the first flush and no need to worry till you empty the tank
I'm sure there are tons of things I've forgotten, but these are just the first few things that came to mind. The first few times you go away for the weekend, keep a pad of paper handy, and eveytime you think of something you wish you had, write it down. Also keep track of the things you brought thinking you couldnt do without. After our first few weeks, we got rid of a bunch of stuff that was never used and was just taking up space.
