I echo what Alex said about collimating the newt. I have one and carry it about the place. Collimation is a 5 minute job done during twilight, maybe 10 minutes if both mirrors have moved significantly but in truth the primary rarely moves at all. If you are only carrying it inside and outside I doubt it will need recollimation once you have it right (including the tension on all the adjusters and lockers).
If that idea isn't appealing how about this?
1) Plan to sell 1-2 scopes to make room (and make cash)
2) Buy the 8" NexStar here:

The total weight is 18.1kg and it can be moved in 2-3 stages. I'm not sure how well you can set up the goto with your limited sky but you have that problem no matter which option you chose.
