Welcome to the site grazer!
I have an '06 Knight PLQ, which is a brother to your coach. Same thing, different nameplate. In my very humble opinion, the PLQ is the coolest floorplan. Ever. We have actually been looking for a new coach lately to upgrade, and have walked through hundreds (or at least if feels that way), but have yet to find anything as useful to us as the PLQ. I have scoured the web looking for a Camelot or Scepter 42PLQ with not much luck
What makes is so great for us is that we practically live in the rear part of the coach. I work during the day, and my office is set up in the rear portion. At night, my lovely co-pilot joins me for some TV or Wii
Can't tell you the last time we watched TV our front. Very cozy back here, temperature stays very constant, and I have everything I need.
Our '06 sat on the lot for almost a year before it found us. I think the PLQ is a very special floorplan, that maybe does not appeal to the masses. In fact, they discontinued it in '08, much to my dismay.
I would work a full service into the deal. I am sure they have probably taken it out to shows, or other lots or something, and it probably has a couple thousand miles on it by now. Tell them they should do the one year service on it at least. The only real problem we have had with our was with the two A/C units. I think they take them out to shows - or on the lot - and run the A/C, then shut off the power without letting them shut down gracefully. We had the two replaced within the first year, and the new two have performed perfectly.
It has been a great coach. Even walking through the 1/2 million dollar coaches, we always walk out saying that our PLQ beats them all. Monaco has been great, the 330 ISC has been all we have needed for a loaded rig and a 4-door Wrangler.
I guess you can call us happy with ours
