I recently purchased a 2006 jayco 20ft jayfeather exp that has a dry weight of about 3550 and loaded weight (gvwr) of about 4550. Can I comfortably tow this with a 2003 ford explorer with a v8 and factory tow package. The tow package includes a 2 inch class III/IV hitch, 3:73 rear end gears, and a tranny cooler. Ford claims the explorer has a tow capacity of 7000 pounds. This vehicle would be our daily driver so I don't want to stain it. Any feedback would be appreciated. thanks
