Most receiver hitches on a 5er are rated 3,000# and 300# hitch weight so a Wrangler would need something more substantial.
Not sure how well something like that would flat tow??? May need a tow dolly???
I do know my combo is a dream to tow with no downside other then being sure wherever I go I can turn around as backing any distance is No Bueno.
The Map shown, YES WA and OR are no Double Tow but CA with an endorsement is fine and they do recognize SD licensed rigs.
I have double towed NW WA to Socal and back since April 2017 with no issue. It saves me $500 each way on transport fees.
