You'll have to cut out an inspection hole (jig saw with metal blade should work fine) then make an cover to go over the hole when you are done.
Interesting to read that you mention use of a jig saw.
I haven't had to cut any access holes yet, but thinking that one day I might need to do so, either for access to the fresh water drain valve or the waste dump valves, I thought that something like a jigsaw might cause a real problem.
I figured that I would probably need to very carefully drill a small hole and then use a hand or air nibbler to cut the opening larger in order to avoid damaging anything.
Maybe first cutting a small opening so I could get a look inside with flashlight & inspect mirror - or maybe my easy hitch infra red camera - to see what obstacles I might face as I proceed to cut.
Is there generally lots of clearance space so that using a jig saw is unlikely to do any damage in these particular areas?
