I have a 2003 jayco Kiwi Travel Trailer. Is this a job I should be able to do myself? I'm a bit worried because of the gas hookup. Would soapy water be good enough to test?
It is fairly easy. My #1 concern would be to get the caulking done really well.
As for testing for gas leaks, I like to use kids bubbles, you know the kind that have the wand. It bubbles up really nicely, and sticks to the fittings, and is really cheap.
