Another for the bottle jack.
I bought one of these and I keep it in the back with the spare tire. I've used it twice on my car and once on someone else's. It's worth every penny. https://www.amazon.com/dp/B00GJJZ5YC/ref=cm_sw_r_cp_apa_fabc_otXXFbBKC998Z?_encoding=UTF8&psc=1
Get him a uni-jack. They are convenient and will make sure he is using his jack stands since it's literally built into the jack.
Doesn't work for low low cars, but anything with 9 inches or so under the vehicle it'll slide in just fine. There's a 6000 lb option as well for bigger stuff

Just some tips if you plan on using that stuff for more than looks (which is fine, I'm not giving you a hard time). These are just things I've learned over the years. Prepare yourself for Some unsolicited advice.
Don't leave the traction boards up there any longer than you'll need them for your trip, they'll last way longer and you won't have to worry about them getting brittle. Lots of people will say it doesn't matter, but any time you can keep something out of the sun and cold it will extend its life. I bought some cheap ones for looks off Amazon, and I keep the nice ones in the garage for my longer trips. The cheap ones will work just fine for most stuff but you'll only get one or two uses out of them.
If you're leaving the shovel, lock it. It doesn't matter where you live. A shovel makes a great tool to break into a car and an OK weapon... The wood on the shovel is probably coated with Polyurethane. It will yellow and crack if it's left outside for too long. I would keep it inside your rear storage if it's not too long. It will last longer. It looks like you live up north so a shovel is a good thing to have, but it would suck if you needed to use it and it's frozen to your rack (which WILL happen).
The tire takes up a lot of room on top. Think about how you want to prioritize your space. Do you want more space in your cargo area or more space on top? Again, living up north, it would suck to have to put on a spare tire that's covered in ice. You might want to consider getting a cover for it, but it might let water pool on it, so that's something else to consider.
Living up north, adding a camp axe to deal with the ice isn't a bad idea either. I keep one of these on the floor between my driver's seat and the door frame with the axe head by the B-Piller. Keep it in your car, it makes a much better weapon than the shovel.
Ditch the scissor jack. Get a bottle jack. They're smaller, faster, and safer. I have one of these, fits in the cargo area just fine (with my tire), and works with any vehicle so you can even help other people if you feel like it. Don't get a hi-lift jack. There is nowhere to use it on your Renegade unless you have rock rails and aftermarket bumpers and even then they are super dangerous. You should really consider getting anything other than a hi-lift jack.
I would get the coolant flushed and changed at 90K, but before that at least get the coolant tested. Make sure you kept topping it off with Subaru Super coolant if it's the original coolant. Else when you flush and change you can use Zerex Blue for Subura which is HOAT base. Can get strips to test your coolant to see if it still has its properties. Also when you do get it flush have them change out the thermostat and make sure they use Subaru OEM thermostat.
Also you can get strips and a device to test your brake fluid to see if it's still ok before having it changed. It will all depend on the climate on how much water get absorbed and check copper content.
Another thing you should high consider is getting the CVT fluid changed and I would get this done at a dealer for your case. It's not lifetime fluid unlike what Subaru America wants you to know.
Of the things I think you can tackle is change the power steering fluid yourself. The easy way of doing it for you would be is buying a manual transfer pump and pump out the power steering fluid from the Reservoir and then refill it with Valvoline Maxlife ATF fluid. Drive around a few blocks and then repeat 5-6 times which should clear most of the dirty fluids from the power steering. Do it every few years.
Your car is long over due for front and rear differential fluid changes. It should be done every 30K miles. Are you comfortable in jacking up your car on a level surface if you have a garage ?
If you want an easy way to do this I got the perfect thing that's an all-in-one Jackstand and bottle jack in one.

Get 4 of those and you can do your differentials front and rear changes every 30k miles.. using Mobil 1 Gear synthetic 75w90
check out the video for diff fluid change..
Also ... if you get those jacks you can also learn to do brake pads pretty easily with rotors ..
You'll also need to get a torque wrench...
Oh I just read.. that you know how to rotate tires so it seems you are comfortable jacking up the car.... then I think you can change your differential fluids front and rear..

I have this dope little combo bottle jack + jackstand and it works great for servicing. I'll probably eventually grab another one to throw in the cavity in back under the picnic table because the stock scissor jack is such a pain. One of the reasons I bought it is because it has a full metal plate on the bottom so you can use it on dirt with no problems, other reason I got it is you can pre-extend the stand part to get more usable throw out of the bottle for lifting taller vehicles (I also have a Fnord Exploder).
Great little jack, used it several times this summer. A little big if you don't have a gen 1/2 with the vestigial spare tire cavity you can stash it away in though.
If you have enough ground clearance, you could use a Unijack.
You may need to drive it up on some ramps first to get that 8+" of clearance.
