The Wrangler is an excellent toad, but there are dozens of other excellent toads as well. There is no shortage of 4x4 with transfer cases that allow 4 down towing. There are also many other types of vehicles approved for 4 down towing.
The best toad is the one that fits your preferences & needs for using the vehicle when its not behind the motorhome. If you need a vehicle to transport a wife, 2 kids and a dog, then the Wrangler may not be the best choice. or if your campground plans usually involve taking several couples to the local restaurant, a Wrangler may not work.
Although I have a Wrangler as my backup toad, I prefer a pickup as my primary toad for the extra bulk hauling space in the bed.
Meeting the 4 down towing requirements is easy these days. The question is how will you use the vehicle after its unhooked.
