This is my first post as we are in the process of ordering our first TT - a Timber Ridge 270DBHS.  We have only tent camped in the past so knowing how long the pad was didn't really matter at the point.  What I am wondering is when checking for length of the pad, should I always calculate the length when hitched together or can I reduce the length because we can unhitch?
Thank you for your help!
yes, you usually can fit in a spot shorter than the overall length. In my case, I'm 60ft overall, and generally can fit into a 40ft site, often even shorter.  First, truck can go is diagonally and overlapping the tongue.  Second, in many cases (but not all!), there is open space behind the pad, so I can back the trailer till the wheels are at the end of the pad, trailer overlaps, probably 15'.  In that case I can fit into a 35' spot.  
But, unless you have a site picture It's hard to figure exactly how short a pad you can fit into.
