1/ Why is it OK to cook inside a trailer tent but not a regular tent?
2/ I assume your car should be fitted with a tow-bar before you get the tent and the tow-bar is not something you get as part of the package? Asking this because a trailer tent came up on my local freecycle and I couldn't respond as I was fairly sure we had no way of towing it away! And it would have been such a great thing to get for nothing!
