I got a response from another site ... FYI ... still looking for some clarification ... since I just dont see any Access Panel on the '05 Intrigue !
"I just went through this nightmare with that slide on my 07 Intrigue and it ended up being not as bad of a fix as I thought…. Raise bags up as high as you can in rear, dump the front, Take that access panel/plate off above tag (heavy and super awkward), all of the hoses meet in there. It’s likely it’s in one of those connections. Under your cans inside there’s an L shaped piece that runs the bottom of your cabs, might be a couple screws hiding in carpet, take that off then Trace line up through floor and behind your wood panels on each side of slide. It’s easiest to remove those wood panels (gently pull off middle strip, should be screws behind that to take panel off). Take line to hydrologic shop and have them remake. Mine was a special 6000 psi line.
Another great point of advice, have them remake all four lines. There are two to each side. Make sure to mark them before you pull them off so you put them back on correctly. I replace two on one side and two weeks later blew the other side and had to do it all over again for that side.
GOOD LUCK! PM if you have any questions."
and a further follow-up from another :
"Shane is absolutely correct. On my 05 Allure I was able to get the number off the line and order it from HWH. Those vertical trim panels that run on the large vertical column can be preyed off easily, mine was held in place with pin nails. The cylinders are a little difficult to get to. If the cylinder is leaking, release the pressure first before attempting to do any repair. After the repair, make sure that you put the cylinders back in place before pressurizing the line."
