I know there are so many great accessories out there, but in my caravanning experience, I wouldn't leave for a big trip without these 5 items:
These little 12-volt fans use almost no power and are whisper-quiet. They are the best way to cool your caravan down if you don't have A/C option.
A super handy other set of eyes at the back of your caravan. Not only used for reversing, but also to see what's coming up behind you when you're driving.
You will need these for a good nights sleep when staying at a campsite with uneven ground. Your fridge will also work better when your caravan is level.
These are great little BBQs that do it all - roasts, grilling, frying - all while cooking everything to perfection. I personally don't like cooking inside caravans because it can make everything smell like whatever you had for dinner.
Although they are more expensive compared to the others - Clearview mirrors are bigger and better than the rest. Having these mirrors makes driving so much easier, and once you have had Clearview it's hard to go back to regular towing mirrors.
