Pure sine or standard inverter
How big of a deal is a pure sine over a standard inverter? I now use a standard 400w to run the TV and direct box it dose fine. I am thinking of a 1500w to power the whole 5er, coffee pot, microwave, ...

I have never run a fan while camping, except the overhead fantastics.
When we bought our KZ Spree years ago I had the dealer install a 3-speed, reversible FanTastic vent fan as part of the deal and except for those rare times it was necessary to run A/C that fan ran constantly anytime we were camping - loved it! :B
Many use one to exhaust air out of the trailer but we much preferred having it bring air into it, would set it on it's lowest setting, and that's how it would remain throughout our entire stay, day and night. Coachmen, in their infinite wisdom :S , chose to not install a vent of any kind over the main cabin area of our Freedom Express so unless I cut my own vent hole in the roof there is no way to install a similar FanTastic Vent Fan in this trailer. :M My solution came in the form of this $30 three speed, reversible, twin fan that is sized perfectly for hanging in front of the window on my side of the bed ... and we use it the same way for the same purpose - set on low, with both fans switched to intake fresh air, and it runs 24 hrs a day when we're camping.
Obviously though, because this is a 120 vac fan , it won't run on 12 vdc when dry camping so I tried running it on several of the MSW inverters I happen to own - runs OK but makes a heck of a squeal. :E We also own a gaggle of table top 10" 120 vac we use around the house during the summer so I tried those as well, with the same result - they run, but squeal noticeably. Late at night when all is quiet and we're sleeping this squealing is really annoying :M ... but I've now eliminated that issue by instead using a true sine wave inverter to power these fans. To date I have this inverter wired to feed the trailer "whole house" so I can plug these fans (or anything else) into any receptacle in the trailer but that does require me to first turn off the converter, force the gas to fridge, turn off the water heater electric element, and go outside to plug the trailer's main service cable into the inverter. I'm now planning to install a few dedicated receptacles in the camper (one of each side of the bed and another by the kitchen galley) which I'll feed directly from the inverter output receptacles. That should make for much simpler use than my current "whole house" wiring scheme - just turn the inverter on with the remote panel located inside the camper and plug into one of those dedicated receptacles.
