If your unit is a two way (propane and 12v), the 12 v will not cool as well as the gas. The 12 v is intended more to maintain temperature when moving without excessively straining the electrical system. You might be able to improve cooling by making sure all connections (electrical and mechanical) are clean and tight and that all air passages are clear of any obstructions.
The same is true with three way units (propane, 12v, 120v) except when using 120v, it should cool as well as with gas. Again, check all electrical and mechanical connections (same as rvpuller's advice) and make sure all air passages are clear. If that doesn't help, you may need a new 120v heating cartridge or other service or, if the unit just wasn't made to run as efficiently as the newer ones, a new fridge.
