ABSOLUTE MADLAB LOCATION FOR YOUR SHOREPOWER. GENIUS

[AwesomeMrKool]

One of the most helpful videos I've seen! Clear and straightforward, thanks👍🏼

[timberbetch]

You have NO IDEA how much this video helped me understand my system! Especially the AC side of things. Your diagrams and product links saved me so much time and energy and i appreciate you giving out this info for free!

[RustyCas]

That shore power connection is the cleanest, least “obvious” I’ve seen but it’s a lot of work - kudos to you for doing and explaining it well. I will do mine this way. Also, your camerawoman is very patient as well as talented.

[TomwithaDream]

Excellent work. Very high quality craftsmanship! And a great job showing how you design the components, lay them out, and show people how to install things.

[RustyCas]

Nice video. Thanks for the detail on connecting the van battery.

[ellobo]

It is wonderful that you didn’t destroy a great tutorial video by trying to record with one hand and manipulate items with the other. All instructional content providers should learn this. Thanks !

[PKsVanlife]

This video is more welcomed than you can possible know!!! Thank you so so much for sharing this incredible electrical system install ❤️. So many of my questions were answered! Yay Nate!!

[eplumer]

This was a very thorough video, well explained! The shore power inlet is genius.

This is the best clip I’ve found that is so understandable It’s so practical. I like how you make it so simple and show little ways to use and crimp ferrules and strip 50mm cable (in uk we have different gaugings and measurements. In fact the US seem to be the only place in the world that is using imperial. Uk is a confused mash of both) I too used the wheel arch box to hide most of the cable behind otherwise it becomes messy

[Geekchica]

You both have done such an excellent job with this video. The explanations were clear, done in a calm voice, and did not use jargon. It was just right for a neophyte like myself. Kudos to you, both!!

I've found that the rear quarter trim panel will easily slide off when pulled straight back (after pulling the rear edge free from the corner panel). I hope that makes sense. Then you can either try to slide the panel back in (it's hard to get every clip engaged) or remove the clips like you did. Your method is probably easier if you have plenty of extra clips at hand.

[MarkSegree]

Nice system. Very informative video and I got all the information I needed. I will say you have a lot of patience, I would of drilled a hole in the side of the van. Still doing my research but this system looks promising for my project

[robertserra]

Excellent wiring, instruction and detailed explanation.

[marctania]

THanks for the great vid....We are about to start out electric today :)

[alanmarronfanning]

Brilliant video mate!!!! Cleared up so many questions I've been considering whilst planning campervan fit out

[dereklyons]

Wassup brotha! I'm diggin' your youtube channel, bruh. Good shit, man. I watch a bunch of van life stuff on YT so it's pretty cool to be following your van life adventures. Proud of you, Nate.

[vudoo]

Your videos are so helpful!! Thank you for taking the time to put together a detailed tutorial video. Really appreciate it.

[BariumCobaltNitrogn]

Minor detail but what you are calling 10/3 is 10/2. The 2 refers to current carrying conductors. The ground does not carry current. Your layout is very neat and orderly, good job.

[kenna]

love your videos would love more day in the lifes
