Don't think it can be towed 4 down trippin. There is a site that has a list of 4 down toads but can't remember where. Think you can put motorhome magazine in search and find it. You may also check with remco and see if they offer a pump or axle disconnect for it.
FMCA has a site listing towable vehicles. Believe Motor Home magazine also has one. Also, Remco is the expert on towing and will honestly tell you if you can tow it or if you need a modification (which they can supply)
