Scottz I have run inverters on every thing in my trailers for years using the stardard modifide wave units. Right now I own 200 watt to 1100 watt inverters for running my TVs to WIFI set up and all inbetween electronics with no ill effects.
The only warnings i have seen has been on chargers for things like call phones and rechargable batteries that say DO NOT use with modified sign wave inverters but I have had no problem so fare with them either.
The pure sine wave is better for motors so they can run more effisentsy but I don't run my washer and dryer when boon docking.
There is always the exseption but I have not come across one yet.
