New Toy Hauler and New to Camping

As you probably know Echo RV is out of business. I wish I could say there was a big user base, but in my search I've only found one other that was looking at them. That said most things like winterizing an RV are universal but figuring out what you have first is the challenge. You need to explore to see if you have a water heater bypass if you use the pink RV Antifreeze. Another way is that can blow the lines out with an air compressor. You can search on the topic and find a lot of information that will help you to do this.

As far as packing it's really up to you. But you can find a list here. There is also a dewinterlize list on that site too.
