I don't know what type of attachments you have holding up your cabinets, but my 1973 and 1960
have 1/8" rivets holding mine up. Things I have in my compartment for my trailers is a battery operated 20 Volt drill with 1/8" drill bits, A cheap rivet gun, for problems like cabinets coming down. I also have a piece of aluminum, rivets, and Sickaflex caulk in my compartment for exterior emergencies.
Last summer a woman slammed on her brakes in front of me on a highway which caused me to hit mine. My trailer jacked knifed a bit and I hit a construction plastic barrel which ripped off my water door. I bought a marine fill valve and cap and used my piece of aluminum and put it all together again while I was camping. I also will check inside for loose rivets, drill them out and put new ones in.
