We hired 3 times before we purchased, after the first attempt we said it was OK but not really value for money, 2nd time it seemed to make more sense and after the third time we were sold!
I think the reason we came round to the idea was on our first attempt we threw a couple of kit bags in the boot and wobbled off to France, camping at sites and eating out every night only sleeping in it, a very expensive tent so to speak. The second time we knew what to expect so packed various bags for the various storage areas so it all made a little more sense, purchased some food on route and did a little cooking and the final time we took our bicycles & running kit, loaded the fridge, hung clothing up etc and really made it ours for the week with some wild camping in the Alps, SOLD
If we hired only the once we wouldn't have purchased.
