Gas vs electric is a bit like Ford vs Chevy.
One consideration is the path from the house to the lake.
Is the grade consistent?
Are there any areas steep enough to require a switch back?
What is the ground surface?
Is it packed well enough to prevent wheel spin or ruts?
FWIW... I have an electric EZGO from Five Star.
This year I replaced the batteries myself after seven years if service.
They cost $1,000.
Another few years may have been in them but I foolishly let the water get below the plates and was concerned that a refill and charge might not work out and we had company coming.
I plan to check and replenish the water in the new ones twice a season.
