Marc -
For what it's worth, we've really enjoyed our tent trailer. It's a big step up from tent camping in terms of comfort, especially when the weather's bad. It gives you and the family more room to spread out, since you've got beds, a table, etc., and gets you up off the ground if the rain's really coming down.
I liked Ali's suggestion about trying the trailer out for a "test tow" with the 60. I think you've gotten the general impression from the group that a 60 with a stock drivetrain may not be the ultimate tow vehicle, but it might do fine for a few times a year until you get your Tacoma.
It sounds like ours is about the same size as what you're considering - I think ours might run 1,350 pounds dry. We've pulled it with the 80 for a few years now, and we've just outfitted the Tacoma with a trailer brake controller, so the truck will likely become the primary tow vehicle. We are going to take the tent trailer to Ruidoso this weekend with the Cruiser, so you're welcome to check ours out if that would help you make a decision.
Also, trailer brakes are a big plus, even with a trailer that small. I used to think that they were probably not necessary on our small trailer...until a lady in a Corolla decided to do a lock-her-brakes-up full stop (from 75 - 80mph) on I-25, in the left lane, so she could do a U-turn in the median. We were right behind her in the Cruiser and we were able to stop in time, but I think without brakes on the trailer, we'd have been in her back seat. I'm still amazed no one plowed into us from behind.
I think you'd enjoy a tent trailer if it seems like the Cruiser will work for you in the meantime until you get something else. I'd be surprised if the seller wouldn't let you borrow it for an hour and take a test drive to the East Mountains to see how the 60 does on some uphill grades.
Good luck - we'll watch and see if you're tent camping this weekend - or tent-trailer camping.
