I've camped in my RV a number of times when the temps got down into the 20's and even sometimes into the teens without any problems, although it's not something I enjoyed and I did worry about freezing water lines. Obviously where the water and holding tanks are and where the lines are run and how well everything is insulated or protected plays a big part in this.
For me a general rule of thumb is it's usually safe unless you're facing a hard freeze which is defined as "four consecutive hours below 25F" by the NWS. Most plants survive light frosts and freezing temps that don't meet this definition.
Camping with the furnace on is drastically different from an unused RV with no heat on.
I wouldn't count on residual heat from the day doing much of anything, particularly in the storage compartments.
Mid to upper 20's is marginal. Good chance it's OK but no guarantees.
