The CRD2 40 is what you choose when rugged portability is a must. For my insulation test, I brought the large compartment down to -18C and shut off the power. Sleeping near the BougeRV fridge — as vanlifers and drunken fishermen are apt to do — is also a mixed bag. Even with all my gripes, BougeRV’s $509.99 CRD2 40 with battery bundle makes for a fine travel companion, especially in the highly portable 40-liter (43-quart) size I reviewed. You buy the CRD2 40 because you’re looking for adventure, and maybe just a taste of self-flagellation.
