Lately, I've been getting advice on how to purchase and install tow bars and base plates for a TOAD (which BTW, is really a FROG... four rolling on ground) . (TOAD actually means "towed on a dolly", which isn't going to happen). I'm going to call Zippy (my car) a FROG because (aha!) it's green.
Unfortunatly, I don't have any mechanical ability or upper body strength and am completely useless when it comes to installing things. I'd be terrified to see poor little Zippy flying off a cliff edge because I didn't have the strength to get the tow bar installed tightly.
I generally use the Women's Guide to Maintenance: if it moves and it's not supposed to, you use duct tape. If it doesn't move and it's supposed to, you use WD40.
Everything else I pay for.
