Gashog, I like the portable unit better on several points but the reason you pointed out is very valid, your not going to be touching the RV wiring so there can't be an issue with warranty. The units come with a metal collar on the power wire; it is a thick flat metal plate between the box and the plug; it cannot be removed without cutting the wire and it isn't going to be easy to cut at all. I bought a 3' section of hardened chain and one of those round locks that do not leave any hasp open for cutting. Once plugged in I chain it closely to the shore power post right under their power box. It can't be slid up the post that way. 95% of the time we are in camp grounds that I have absolutely no worries about, but the 5% is the time I like my chain. Also, with the portable, you already have it for your next RV, and you don't even have to pull in to check the power. The Progressive units are rated for use outdoors and mine has been in several rainstorms without issue. They tell you it is water proof, but not to submerge it. I am thinking that if it gets submerged while connected to my shore power post I have several other issue even more important, such as my RV does not have life preservers on board. http://www.forestriverforums.com/for...ilies/wink.gif
