Ha ha ha ha - all been there done that - Posting I am refering too.
And quite frankly not everyone has 100's of house to research through tons of threads - especially at this forum - where many times to get to the point you have to wade through some pretty weird antics of most
Also that is what the moderators do???? correct the newbies fauxpaws - meow
So don't feel slighted Maya - just keep going ask away - and those who have the time will provide you with the answers you are looking for - or will at least provide you with a link to a good thread that can answer your questions.
You might want to back up a bit and ask yourself what type of camping you will be doing with your trailer - then purchase and install the systems best suited - ie. full hookups all the time, boondocking, - seasonal spot at a trailer park etc.
And of course when you are ready flood the questions you can give the potential answering parties a bit of back ground as to your needs or chosen needs.
But most importantly - NEVER stop asking questions!!!! fire away - what is that commercial - "in a perfect world" this forum would never have a repeated questions
Welcome to the forums and good luck with your restoration!
