We looked at the Compass before buying our signature rig. We liked a lot of things about it but for us it wouldn't work.
1 - Didn't want the Mercedes. We live in the hills (pacific northwest) and the small diesel V6 didn't do as well in the hills/winds as we expected. Didn't want to have to rely on it as primary transportation on the road, and it is weak for towing a toad.
2 - A servicing Mercedes dealer was a couple of hours away.
3 - Gas engine was cheaper and easier to maintain, not to mention more powerful.
4 - No cargo carrying capacity, and unless you get the twin bunks model there is nowhere to put anything. We average 160 days a year - the Compass/Synergy was too small.
Don't know what your budget is, but we paid $104K out the door for our rig with an 8 year warranty. Winnebago quality trumps Thor handily I'm sorry to say. Ours has every option except on-demand hot water (didn't want it) and roof solar panel (we'll have a portable).
Plus it has 2600 pounds of cargo carrying capacity, a huge trunk, and can tow a car.
Don't know what your intent for the Thor was - weekends, whatever.
We liked it but it wasn't for us.
