Having towed many vehicles on full trailers in the past…It would be recommended that you DEF. get something V8 that can properly tow. An explorer/blazer just doesnt have the nut to get there and back safely…trust me I know…and when Mr. Tow comes out to drag your weak 6cyl SUV and your trailer w/ your car…its not fun.
I have had great success towing bigger distance with…Tahoe, F-150 either 8cyl, Chevy 1500.
