Its very evident that several of you that have "looked" at jumping Jacks and have discounted them as not worth the money because you feel that the quads/bikes over the top will leak and damage the canvas, have not looked too close. The JJ's tent is stored inside a heavy zippered container that resists fuel and oil spillage. I have carried my quads several times and have spilt fuel during filling and such with no adverse effect on the JJ.
As for worth the cost....well, that is kind of a relative term, I have wheeled that trailer HARD (for a trailer) behind my Jeep and have not had a problem yet and I can put two Big quads on top and still go way back in where most camp trailers will not, including a lot of the new full body tent trailer that claim to be off road friendly (meaning they are ok on a dirt raod).
Yes, they are pricey, but only have the cost of the adventure trailer and I can sleep twice as many......o yea, and try and get a quad on an adventure trailer!!!!
