 First of all, thanks for all the replies. Just signed up for this forum and already it seems very good!
Tomorrow I'll experient moving the sub around. I'll make a new spreadsheet starting off at 20hz.
I could consider a new sub for sure. One thing I havent mentioned is that I'm building a house, but not moving until 9 months or so. I havent decided on what to get for my setup in the new house, but I was possibly thinking something like Velodyne DD 15 or so. Until I move I'm reluctant to invest in the wrong sub that I cannot take with me into the new house. However as I crave for better bass I might buy it sooner rather than later and risk it.
I would definately consider using the software you mention, however I thought I needed the BFD for it as well? I could easily buy cables and such and I was very much considering the BFD. I am however a little worried it will be too complex for me.
Yes, actually I've stepped all around the room, it's simply quite amazing how moving 2 feet can make for instance a 30hz sin tone disappear completely.
Moving the sub to the other side might work, however, it will be near a door and we're entering the whole WAF issue then. Moving the coach is not an option really, there's some furniture beside it. My crude drawing did not show this - sorry.
As mentioned above in my reply here, I'll try moving it around tomorrow and do some tests and see if I can find a spot with few dips and an even curve.
Thanks again for the inputs so far, really appreciate it.

The DD-15 you are considering is a honey of a sub and it has a built-in system for measuring and eq-ing the sub. It ain't cheap, but it's a good sub.
The REW software does not actually do the eq-ing, but it measures the frequency response and calculates the filter settings to use on the BFD to get the frequency response you want. I'd suggest starting out with some REW measurements along with some placement experimentation before eq. You may be able to get a big improvement without any eq.
Also, experiment with the phase of the sub. Somtimes the phase relationship between the sub and the mains can cause bass cancellation in the crossover region.
