Congrats on your new purchase! You're going to love that Outback. We have the 298RE (Rear living room with windows on all sides. Kitchen is in the middle, no island. We've enjoyed this camper so much! By far the best one we've had yet. Not only for the space, but the camper itself it is very good. We spend a lot of time in it, and we've traveled a lot with it. Actually, we slept in it last night.
Your's is 37.4 feet long, mine is 35.5 feet. We use an Equal-i-zer hitch also. The camper tows great! Not ever a hint of problem. We have an integrated brake controller and tow with a diesel 3500 duly. The ride is flawless. I'm sure yours will be too!
The only thing you REALLY need to ALWAYS need to be aware of is the actual length behind you. Be aware when turning sharp turns (like in town at intersections) the trailer rear has a wide swing. But we have NEVER found ourselves in a situation where this was a problem, but by planning the turn as soon as possible, or just taking the next intersection can make a BIG difference. (we've driving straight through some intersections in town where we wanted to turn, and came around a different way, but here again, never a problem).
Good luck with your new camper!
