We can set our 2010 Hawk up whilst still hitched to the D-max, and have done so quite a few times when a quick overnight stop was required on our trip last year. The front bed on the Hawk is the same size as a Swan. We have the std drawbar length. Easy way to check if possible - take your car in, hook it up, wind it up & slide the front bed out.
Re the couch at the kids end, we haven't found this an issue, they go off to sleep with the curtain pulled, and we don't have a tv camping, so we are either outside (warmer up here) or in bed. The curtains are block out material in ours, so handy.
The couch also means they can actually get up into their bed by themselves. We have simply got some cheap doona covers and put the cushions inside these. The cushions are still like new after our 15 week trip living out of the Hawk.
Couple of other things that swayed us to the Hawk layout, apart from ones mentioned in the other thread links the cruza driver posted;
- The fridge on the left side means that the vents are shaded by the awning most of the time. As mentioned, we lived in ours for 15 weeks straight, and the 3 way fridge works best when cold air can get in and hot air can get out of those vents.
- We stack the fridge at home the night before we head off anywhere, and when the camper is down, it helps to have it close to the door (Eagle is also ok for this)
- The outside locker located at the rear is used as a food pantry for us, as we prep & cook outside, and this would be a pain if it were behind the door.
We have roller draws in the back of the ute, and our clothes were all in there on our trip, otherwise we just have soft bags that sit on the couch or bed when camped for short periods.
The price on offer for that Dove OB is good, so would be hard to go past. We looked at that model also, but felt the extra foot in length and the larger seating (our Hawk does not have the cupboard by the door that the 2011+ models have) would be good....that and also that we got a deal similar to yours as ours was a runout 2010 that we picked up in Jan 2011.
Check out our blog link below for some pics etc. or feel free to ask away about anything else - we've pretty much done it all with the Hawk, so should be able to answer any questions
