I have this same exact issue.

same issue here, can install and uninstall a television and radio, but no options for oven and fridge

it's like a hit or miss for me. I also have the cheat menu to spawn vehicles. I spawn a trailer, it sometimes works or sometimes doesn't. When I find a spawned trailer by the game, it sometimes works and sometimes doesn't.

Same issue

change your seat to gain access to fridge/oven

Nope, it doesn't appear so neither...

Not sure if this helps, but I found a "Compact Fridge" on my current playthrough, It says "it can be installed in some vehicles and trailers" when you hover over it. I haven't tried to install it in any of the campers but is it possible that you need one of these items? I cant place this thing anywhere like a mini fridge, but I also dont have a camper or trailer it seems to fit, something to consider at least

Microwave and refrigerator are integrated into all campers and do not require installation. Make sure you have the "Tsar's Common Library" mod enabled in your save. https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2392709985

Thanks for the answer, maybe that was the problem...Is there any way to spawn them without having to find them on the map to test them? Thanks!

necroforge mod along with it's extension (more vehicles mod) is able to spawn them

I just downloaded necroforge but I didn't found any extension, I only found the cheat menu extension for vehicles... Is that what you mean? Thanks a lot.

@iBrRus, I also found an iLYA-1990 at a car accident scene, which I towed back home for repairs, but likewise I wasn't able to see the fridge or the stove on the radial dial menu. I already have Tsar's Common Library installed (and I believe it's the latest version). Do I have to switch seats like what @thine_pale_one said before I could access these appliances? Or, do I have to unsubscribe and resubscribe to Tsar's Common Library for the stove and fridge to work? Or, should I install a compact fridge and compact stove to the trailer since it's in a completely beat up (but not wrecked) condition?

*EDIT - Problem solved! Yes I indeed have to change seats before I could see the fridge, stove and microwave. The only thing left now is the weapon rack which I'm still trying to find. If anyone has any clues, please shout out, thanks.
