I have a 2014 Jeep Wrangler.
The 3.6.
I like the motor but yes towing does drop the gas mileage.
A couple to three extra litres per 100 k isn't unusual.
And the Wrangler isn't the greatest mileage to start with.
I pull a trailer with a snowmobile or an atv, Sometimes a tent trailer.
bigcreekdad in Canada adding a electric trolling motor also makes it a power boat.
Just not all power boats require being registered.
But you still need a PCOC to operate a small boat with an electric motor.
Lots of structure in the lake. Also can boat into Rabbit lake.
Lake has walleye, smallmouths, pike, lakers, herring whitefish.
For some reason around 20' seems to work good for walleye.
Most of our walleyes come from trolling worm harnesses or still fishing at dusk.
Where are you staying?
I never heard of anyone one being charged for that combination but I believe technically the combined power of both motors may put you over the power limit.
