I have the same thought as everyone else. My sewer has not been bad but, I did get all backed in and then just before I unhooked I had to move up to get the power hooked up. This put me close enough that I had to keep the truck under the 5er to be comfotably out of the road.Well, Not UNDER the 5er ( I know how this board works ) but I left the truck where the pin was within an inch or two of the hitch. Anyway, the Extension for 50 amp was a little pricy so I never got it. Good thing to, the new coach is 30 amp, now I'll get that extension. I keep 100ft of cable wire (helps to have a friend in the cable biz ) and I keep extra sewer hose that I haven't needed but just in case. Most of the time I figure I would rather store an extra 10ft. than need an extra 6 inches. By the way, my friend with the Cable Co. told me his parents have a coach and at other parks have had the cable not work and with the extra coax could use the next site and not have to move ( I'm normally set up by the time I try the TV ).100ft may be overkill but more than 30 couldn't hurt.
