my mom had one of those Elans..............man could that thing so through snow. she used to bust trails with that where noone else went. our first encounters with snowmobiles was a scorpion, then a big polaris charger, man that thing was heavy. the rest have been ski-doos. i currently haver the formula s. but in between the TNT's served us well.
2021 update, solar panels still going strong. Only thing I had to do was replace battery bank last year with new gel cells. I have had zero regrets on solar. The house is always ready to go when I get out.
One great enhancement that I added was a wifi repeater with an external antenna. This lets me grab internet from the cabin and repeat it inside my fish house. With that I added a wifi thermostat so I can turn my heat on remotely and I put a ring doorbell cam on my door so I can keep an eye on things outside. Added benefit of good wifi is that I can work “ remote” from the ice fishing house.
