2020 jayco eagle 347BHOK

[Kleinajk92]

Ok so need help! Wife and I are getting a 2020 JAYCO EAGLE 347BHOK. We will be selling our home and living into it. Won't sell our home till at least March as I am currently deployed. We plan on taking it out for summer and weekend trips, while living permanently all other times at the base I am stationed. Have questions about what I NEED and what is nice. Please add links to things as I don't know the lingo or acronyms of this stuff. We are watching a ton of YouTube videos as well. Here are my questions.

What do I need to hook the electric to house?
What additional items do I need to buy?
What are things to avoid buying?
What insurance do you all use?
How and what do I need to hook the black tank to house sewers?
What is a resource for finding all about this trailer? Like the width with slides out.
What du you use for internet? We run an online business and need good internet.
I am sure I will have more as you all help me. Thanks so much for the advice!
