I'm going to say camping for a few days with a hedgehog sounds complicated but you mentioned months? If you're in a trailer with electrical its probably a significantly easier task than if you're portaging and tenting in the back country.
Where I live, even on the hottest summer night, the temp drops an awful lot at night. I'd be checking to see how I can mitigate a lot of factors/risk: escape, temp fluctuations, food/water quality and storage.
We're taking our hedgehog to the cottage this summer for 2 weeks. We're bringing everything we have for her. But we're leaving her with my mother when we hit the provincial parks for canoe camping.
