I would - cold = condensation = rust.
I'm using thermoliner in mine, and everywhere is covered except the wheel arches. I'm leaving them until last as I don't want to risk tearing the insulation when I build my bed and kitchen over the top of them. I'm going to build the frames first, then insulate the wheel arches just before I fit them. I intend to carpet the arches too to protect the insulation.
Thermoliner does not stretch around "outside" curves - the adhesive may not hold, so I'm going to use Thermoliner on the flat bits of the arches (front and top), and some of the gold foil faced foam and Trimfix around the tight bends for this job. It won't look too neat, but it's going to be hidden so no worries.
