So i opted for the on board compressor but haven’t used it yet.

In the cargo area, opposite of the compressor (which is on the drivers side)....is a plastic “shell” mounted to the passenger side in the same
spot as the compressor. it has a hole in it toward the bottom.

does this thing serve any purpose? Thanks!

 

Electrical relays and fuses

 

thanks!

 

I am considering the air compressor. Does it eat up much storage space? If it is not too much trouble maybe a picture? Thank you.

 

I don't have any pics readily available, but it is about the exact same size as the fuse box on the opposite side. I really lost no storage space at all.

 

As usual powerfuluk has you covered...

UPDATED with the right video...

 

Thanks all. Appreciate the replies.

 

This was a useful video and, if you'll allow me to geek on it for a few minutes I think it shows why it's not a good value for on-board air if you're serious about airing down/airing back up on a regular basis.

In the video he states his tire was at 35.5 psi and set the pump to bring it up to 39 psi. That's just 3.5 psi more. The pump took from 6:23 in the video to 7:13 or a total of 50 seconds to add 3.5 psi.

Extrapolating from that we get ~ 14 seconds per 1 psi of air.

If you aired down from ~50 (heavy load) to 18 (off-road) that would mean each tire would require 32 psi.

32 psi x 14 seconds per = 448 seconds or 7.5 minutes for a single tire.

448 seconds x 4 tires = 1792 seconds or roughly 30 MINUTES to air up 4 tires.

Not impressive.

By comparison we used the public air pumps to air up when leaving the beach/dunes a few days ago - took 30 SECONDS per tire. And since there were multiple hoses we actually had two hoses going at once. Meaning we aired up in ~2 minutes, but it could have taken as long as 4 minutes if there was only one hose available.

I think I'd rather buy one of the higher output Viair portable units (and besides then it could be used in any of our vehicles): https://www.viaircorp.com/portables

 

I agree. The LR compressor looks nice, but I think if you are really looking for a practical solution when you air down for offroading, it's got pretty low value for $. I have been doing research on this for the past few days as I do need a compressor, and I am going the portable route as it provides more flexibility at much better prices.

 

You forgot to convert from UK to US psi.
