First off.. Welcome & congrats on the purchase.. It was 2 years to date that we did the upgrade from tents to hard walls. Never going back (unless I'm in the doghouse some night
)..
Second.. Where are you located? and where are you camping? You mention Kimberly, your tow vehicle should be ok for short trips, but if you're in the mountains alot you probably won't be very happy at all.
Let me put it this way, I've got a smaller trailer, and tow with ~100more hp/tq w/6sp auto and there's "hills" that I can barely keep 70km/hr.
I camp regularly in Koocanusa (u.s. side) & the Rockies for comparison. Now if you aren't in a hurry (like me), then it shouldn't be an issue, just be considerate of others (ie. pull over when safe to let them pass).
I'm not trying to scare you at all, just letting you know what you'll be experiencing.
A couple things that are worth mentioning.
Since your 4runner is 14yrs old now, make sure everything from frame/tires/brakes/battery/alternator/etc. are in tip top shape before your first trip, and do a complete fluid change (oil, coolant, diffs, tranny), and while they are doing that get them to add a tranny cooler & tranny temperature gauge while they are at it. These two things will save you a ton of money in the long run, and will ensure you make it to your destination safely. The last thing you want is the transmission to overheat, and you end up canceling the trip.
Last but certainly not least, join up with goodsams or AMA
