Watch the weight... The higher end tow dollies with the brakes are well over 500 lbs. The 2009 HHR is over 3500, so combined you are over 4000. Load some gear and gas in the HHR and you get the picture.
Most of these Ford Chassis can only handle 4000 on the hitch.
The US gear system is easily removed from the vehicle. Granted it took me a solid day to install (just me working), but I can move it to another vehicle without problems.
Also watch where you store that tow dolly. Keep it dry, clean, away from animals, keep the tires out of the sun, test it often and make sure nobody can steal it. I test my Saturn 5 days a week on the way to work and it has a handy security system.
The tow dolly is the only way to go if your unable / unwilling to modify the TOAD. Otherwise 4-wheels down (with the good braking system that uses full power brakes on the TOAD & keeps the TOAD battery charged) is the all around best option.
