High-Lift mount to rear bumper. I have both the 48" standard and the 60" 'extreme'. The grey extreme is what's shown below.
Guess what I found out today: oddly their step lift holes are not the same size or spacing. Strange but probably something to do with standard vs extreme in the casting. The head is the extreme so i need to also make sure it ratchets properly with the 48" if I want to have the option to chose either bar.
I have considered the standard bull bar mount which I don't like either blocking the best view of tight terrain or being up there potentially grinding into trees or whatever, or collecting bugs on the highway.
Nor do I like the roof mounted ideas for such high weight. I have tried to keep anything heavy low and/or central as I enjoy high angle routes but with the confidence of lowest center of gravity I can achieve.
Obviously there is also the popular vertical mount to rear swing arms and I've taken some measurements to see about a horizontal approach to using the tire carrier swing arm.
However, this 'plug-n-play' idea just occurred to me yesterday so I thought I'd just give it a try to see how it works. Seeing as it required zero anything except having the right stainless hardware bits in hand, which I already did. These sweet tidy little mounts I've had for all 10 years...just waiting for today apparently. LOL
This option clears the departure angle set by the fuel tank and spare tire but it's not quite ideal if getting crazy with ledge drops or steep uphill transitions, but it is cool as it simply uses the pre cut holes for parking sensors with centering done via a washer with 30mm O.D. That happens to just snug inside hole.
Kinda cool anyway.
It should be noted that I normally carry the high lift inside located behind and below the 2nd row seats. Separated from the bar, the lever and head sits in the floor tucked against the 2nd row seats when folded flat or even upright. The 48" bar will lodge tight between the wheel arches but also still below the virtual cargo floor level.
It has stayed there for years, completely out of the weather and with its dense heavy mass about as low and vehicle centered as possible. My idea is that most of the time, it would remain there for obvious reasons. However, when needed in nasty conditions, or if anticipated repeatedly, then an exterior mount is desireable until such event is finished. Of course this asproach to temporary accessibility lends itself to the above mentioned location options seeing as they would not be permanent.
Still, my preferred location if I can fabricate it, would be rear bumper area horizontally attached to the spare tire swing arm. That would eliminate any aspect of how these photos show potential for departure angle problems.
For the interior, I am devising two similar large gauge wing nut mounts to hold the 48" bar snug so I don't have to use a tie down strap which is secure, but annoying to manage.
I forgot to mention the obvious but important fact that being hit from behind by another vehicle would not be cool if the jack were there. The idea would be to only use those alternate exterior locations when off highway though. I'll probably consider the front bumper if I can't pull together a horizontal tire carrier mount. - on second thought, I'd rather have this table on the tire carrier so I'm going to abandon that idea.
