The one thing that discourages me from campervans is that once you are at your destination you have to pack up every time you want to drive somewhere, unless you strap bicycles or small motorbike on the back. If you're at a festival or can use public transport that's not so relevant. Rather than tow a big caravan I use a fold out camper trailer. It's more comfortable and better equipped than a tent and more flexible than a campervan.

How about hiring a campervan for a weekend away and see how it works for you, and what features are important to you?
