Well, due to your 4Runner, I would say "neither", also. Sister's family has a 4Runner, and a Hybrid TT. Don't know the make, but it is about 20'. They could not tow up a maintained gravel road while towing, and I had to pull them up. Yes, it was steep, but the trailer was too heavy.
As said, a dry wt of 3800 lbs will be near 5,000 when loaded. Your max tow is 5,000, which means you will be struggling up hills, and lots of weight pushing you down the hills.
Maybe, consider a
TrailManor 2417, which is equivalent to a 24' TT. It tows like a popup, but it has no canvas. Dry wt is under 2,300 lbs, and loaded is 3,500 lbs. I have one, and we love it. Depending on your height, though, as the ceiling is 6'4". We are under 5'8", so no problem for us.
My point is, there are lighter trailers out there, that won't hit your max tow limit, which will make you happier on the road. And, folded for travel, there is less wind resistance, which will also make towing easier with the 4Runner.
Good luck with all the options to consider! For the length of your trips, I wouldn't come close to max tow limit. You will regret it.
