1. Can I learn to drive around with it?
Absolutely you can learn!
2. What’s the best way to learn?
I don't know about best, but the CAA offers an in person course for members and non-members. There are also many online training schools, youtube videos, etc. If you have a parking lot available, have a friend with towing experience drive you to the lot and walk you through basic steps including hitching, de-hitching, backing up, parking, etc. As far as the actual systems in a trailer, the CAA course covers that or someone who owns can show you. It really isn't that difficult.
3. Do I replace the carpet?
That depends, do you like the carpet? Is it glued down or loose? I don't know if Eggcampers would be the same but my boler's floor is gel-coated
fiberglass.
And welcome to the Egg family!
