If there are any threads that discuss any of these, please feel free to re-direct me.
1) Jacking on sand/beach:
what do you recommend I should carry in the odd chance I need to jack it up on the beach?
Would a piece of plywood of a certain size be a good "shoe" for the jack,
or are there smarter ideas.
2) Recovery points
If I did manage to get it stuck, where can I safely attach a tow-strap or winch hook to extract a L Series.
I don't want to go ripping parts off of it, learning by trial-and-error.
Should I get my own recovery points and attach them somewhere to the chassis/body?
3) Does a L Series have a chassis, or is it a unibody construction?
4) LSD's
I've heard a lot of people mention adding in LSD's into the rear. Has anyone tried adding an "auto-locker" into the rear? There are many "plug-in" lockers available for rear drive trucks, jeeps, utes etc. that allow full locking when going straight, and unlocking of one or both sides around corners, with the only disadvantage a light clicking sound. A Limited-Slip-Differential works by adding friction, and this extra friction can decrease fuel economy, rob a marginal amount of power and you can have LSD clutch wear over time. An auto-locker isn't supposed to get much wear at all, plus it has no effect on friction in the drivetrain; no power/economy loss.
5) Aluminium bumpers
My L Series has an aftermarket front bumper with an integrated roobar. It feels very solid, has good looking welds and presently is in good shape. But aluminium is known for corroding VERY FAST in a salt-spray environment. Should I coat my front bumper with something to protect the aluminium? I would like something that is clear, so it looks the same. Does anyone recommend a product for protecting aluminium from beach environments?
6) Body & under-body
Do any of you use coatings to protect your subarus at the beach?
I think the reason my Subaru is in nice shape is it might have not seen much beach-duty and is from South Australia.
7) Interior Lighting
Is it easy to add lights connected with the interior lighting, so the floor can be lit up when the door opens?
I find the factory interior lighting pretty poor.

I might need to add one to my car when the SA Rego expires. Are there any cheap ones approved in WA that are easy for DIY installations?
9) Random electrical mods

Has anyone installed their own electrical modifications? I might like to add my own keyless-entry if it doesn't cost too much. It can save the paint from fumbling for the keyhole, plus it's great when your hands are full. I learned to love keyless-entry from owning a 08 Civic.
That's all I can think of for the moment.
I wanted to post it here rather than in multiple sub-forums in case I forgot what I posted.

Cheers
