I am always towing something and usually have two dirt bikes crammed in the van also. In the summer I either tow a 20 ft comp ski boat or our 28 ft crusier (heavy). When we are headed to a lake. When wheeling I am either towing one of my two built boxstyle broncos or the exploder on a 18 foot float, one is way heaver than the other with all the goodies full exo four link, aod, 205, blah blah heavy. The other is close to a stock configuration weight wise.
Live in Co so pretty much every where is up a mountain.
