We downsized to a Class B Pleasure Way Lexor from a Class A and Chevy HHR toad. Kind of missed having a toad even though the Lexor is so easy to handle and park almost anywhere, so we recently picked up a clean '13 Smart Pure model. Simple and compact. We actually replaced a GEM golf cart with it (Smart is same length, a bit wider) but, not a golfer and only needing a local runabout, having an enclosed air-conditioned automatic virtual golf cart was right for us. So, the process of making a toad out of it. Thoughts or recommendations are welcome.
First, I checked the base plate setup. Since I already had a Roadmaster tow bar, I downloaded the RM instructions for the Smart base plate. I installed the base plate on my HHR myself, but this looks a bit above my comfort and available tool level, so will defer that to a tow shop. Also the fact that that supposed 4.5 hour installation took me 4.5 days.
Then I studied the brake/tail light options. I will get a quote from the tow shop to install the diode kit in the rear lights with a plug-in socket in the front grill. If that is not reasonable, I will go with some good-looking LED add-on lights I found on Amazon. To be decided...
From what I have read, the Smart is actually easier to configure for towing than my HHR was. Switch on, wait for electronics to set, put in Neutral, switch to first off position, disconnect battery, put a bungee on steering wheel to return front wheels from sharp turn.
So, my first job was to install a battery disconnect switch. I got a switch with bracket from Summit Racing that I thought I could best install under the dash on the passenger side since the battery is under the passenger foot area. I got some 4 AWG wire at Home Depot (they didn't have black) and some terminal lugs and made my own cables. I just reused the original negative cable from the battery by taping the end off and tying my cable in with a splice nut. It is working well and the switch cannot be seen unless you crouch down, but it is easy to reach. Couple of pix below.
