There are many different sizes and models of Bigfoot truck camper so to answer your question, I'd need a model number. I've had three so far....Bigfoot is a local companty and I've done work at their plant in the past; they are actually known primarily for their truck campers. I currrently have the largest truck camper they ever made which is a 30C10.11 c/w R12 insulation, basement, double pane windows, generator, microwave, skylight, awning, electric jacks, etc. etc......it's just about 4,000 lbs all loaded up and no, I wouldn't haul it on a SRW truck. My Ram is a 3500 dually and I've upgraded the overload springs.
