I've seen the front wheel towing systems and it just does not look safe or practical. I guess if I was rescuing myself from a breakdown, it might be handy, but 500 miles, not for me. Thats all day or even two days traveling. I have the HF 4x8 folding trailer and have used it several times with the RE. Added decking, a removable wheel chock and tie downs and its good to go. Very sturdy and folds standing upright against the garage wall. I've also got a small Toyota SUV with a 1000lb tow rating. The tongue weight on the HF with the RE on it is less than 100lbs. Yes, it takes paper work for registration, tags, etc. but I recently made a stack bed fence system using 2x4 posts and 1x4 slats and can now use it for hauling lots of other stuff.
For my big cruiser, I have a tailgate wide ramp system for my Tundra and I load it in the truck bed for long trips. I tow a travel trailer for vacations, as I'm not comfortable with dual/tandem trailer towing.
