Exciting times! Is this your first Caravan?
A pre departure check list is a top tip from me! I had a sticker in the window with all the usual check bits on. I then found an app for my phone (Caravan Buddy) which i absolutely love! You can make your own check list on it specific to your Caravan, for example i have put turning the motor mover key off. I have found it really handy for me.
My second tip is on careful loading of the caravan. When i got my second caravan, i moved some items to the back of my caravan to lighten the nose weight to 75kg. However, i found the caravan was more unstable and moved about a lot more when towing! I now have very little at the front to get my 75kg nose weight, and put all my other bits over the axel or in the car, and the caravan is now very stable when towing. (I don't carry that much, just aquarolls, wastemaster, a couple of small chairs and a tool kit). The aquarolls and wastemaster made the difference between a stable and unstable tow depending on if I put them at the back or the middle. Once you have figured out your nose weight and safe loading for stability when towing, its done to be honest, i just occasional check my nose weight now a couple of times/yr.
Good luck and happy caravanning!
