What would make the perfect all around tow vehicle for the boat at the lake/river? When you are at the lake it is nice to be able to back the trailer in and out of the water at the shore line without getting stuck so 4x4 seems a must. The longer the wheel base the better I would say to keep those front wheels from even getting in the water. It would have to be something of a beater so it could take the abuse of lake camping without the worry of scratching the paint or getting mud/dirt in it. A camper would be nice so you could have a bed and even a toilet. 4x4 RVs are hard to come by and expencive. I would say the best over all tow vehicle would be a truck camper. This would be good for the river too as you could hook up the RV connections at the RV park.
