Carrying extra lp tank
My rig is a Lexington B+ . For a long stay I have been carrying a extra 30 Lb. LP tank. I was towing a pickup but have since have gone to a Jeep Wrangler Unlimited. I'm thinking of carrying the extra 20 or 30 lb. on a cargo carrier mounted on the receiver hitch of Jeep. What is the laws on this. Better to be out there, then inside the Jeep.
