Tell seller that you want to be sure the fridge is cooling properly in 110vac, propane and automatic modes so have rig connected to shore power overnight before your PDI. Have them check the house battery(s) and converter charger to make sure that the 12 volt DC system is working properly and house battery is good. During PDI turn all faucets and flush toilet to make sure that fresh water pump is working and shutting off properly. Have them start the RV generator and run the roof AC and microwave at the same time using the inside generator switch and tank fullness monitor panel. Find out if you have an automatic transfer switch when using the generator or if the shore power plug must be plugged into the side of the RV generator and have them demonstrate that. Have them demonstrate setup an takedown of awning.( Recommend you add a positive awning lock device to prevent awning from unfurling) Find out if your engine starting battery is kept charged when your rig is plugged into shore power, ( Many RV's don't have that feature).Make sure that all tires are less than 5 years old by date codes and do not have cracking of side walls. Of course take your time and test drive the rig listening for any strange tire or transmission noises or feel any handling or brake pulling or stopping problems. Don't sign the sales contract unless you get promises to fix, replace or upgrade things written onto the sales contract.
