Thanks gbatejan...that's exactly what I ended up doing. The double zippers worked out great and ended up being the perfect spot for the battery tender cable. Sorry for the delay mykes, looks like Jimbo took care of you. John at Pineridge is a good guy to deal with. Hollywood, thanks for the input. In last 10 years, I've never had a problem with any battery I've left on a battery tender over the winter. Just never used the carbag before. Bagged the Viper last weekend. Took hours to get it ready...took 10 minutes to bag it. Doesn't take up much more room than the car and safely tucked away. I'll sleep better knowing hickory nuts aren't in my valves
