srj-1, Are you looking for an axle jack? The rule of thumb is to get an 8 to 12 ton hydraulic jack that will fit under the axle or suspension on that side with a flat tire and whose height will fit on a 12 inch square jack board and under the axle/suspension part. The ARB and Safejack systems look cool, but where are you going to store them, and are you going to wait for the engine and exhaust system to cool before using? Another option that you can cross off is the use of a high lift jack. It will only work on the front bumper with a truck camper; not enough use to warrant even carry it. If you have a flat or are stuck what you want is to get that one wheel off the ground so you can change it or pile stuff under it to get out. jefe
