BB l5, I hear you loud and clear. Opinions abound about what you can and cannot tow with what truck etc. After reading a bunch of these posts I became concerned that our truck might be inadequate to pull our 5th wheel. My husband reassured me that we are fine and that he knows exactly how much we can tow safely and he would never put us in jeopardy, although I am sure there are a lot of people on this site to who would vehemently disagree with him.
We have towed our 5th wheel up mountain grades and all over the west and never had any problems. So I am going to relax and just enjoy the ride.
Best of luck finding a camper that meets your needs. If you're going to park it then I would get the biggest and best built rig your budget will allow.
I have noticed that Forest River now makes "cottages" for people like you who want to park them in one spot for a long period of time. You might check their website....they are beautiful and much more residential in look and feel.
