>>967287I have an '05 Outback which I've car camped with many times. I never did any permanent mods to it, but I keep essentials like canned food and granola bars, water, and warm clothes in the storage compartment under the trunk, right on top of the spare tire. I also installed a CB radio, and will be buying a GMRS radio for it too. Antennas are quick-release or fold-down, and I mount them to the roofrack. I see no reason to camp on top, as it's very comfortable to sleep in, especially since the rear seats fold down completely flat.
If I off-roaded more, I'd go for a 4" lift, brush guard, and some bash plates. I would absolutely love to build a rear swing-gate spare tire carrier for it, then have more storage in the spare-tire compartment, or use it to house a battery bank and stick a solar panel on the roof. I definitely wish it had more power for its weight - mine is the 4 cyl which had like 185bhp new. I keep in good shape, but there are times when it struggles off-road, so go for the 6 cyl or the XT.
