I was thinking outloud that I could run say the micowave if I needed to with the invertor. And wondering if this scenerio would help..
Batts somewhat charged
Solar putting say 15 amps into batts
Truck plugged into camper with enging running.
Would the above help?
Or should I say forget it and not think about running hi draw stuff and just save money and go with the 1100 watt model..

In a really critical situation (read - running a furnace when it's below 30F day and night, or trying to put some charge into batteries after a week of non-stop rain) - perhaps. Otherwise - doesn't sound like a good idea.
Forget it, install a 1000 watt PSW inverter, and keep your maximum draw below 80 amps max, the less the better. That will exclude using a microwave oven but you can easily run a 750 watt toaster or small 550 watt coffee maker as I do, even a hair dryer as long as it's set on a LOW heat setting. And forget solar for load supporting an inverter - it's there solely to restore your batteries, not to power anything directly.
I feed my own 1000 watt PSW inverter with a single G27 battery - when fully charged it will easily run the coffee machine but excessive voltage drop when running the 750 watt toaster causes the inverter to alarm. I could solve this by replacing that G27 with a pair of 6 volt GC-2s or pair of G31s but why would I when we rarely dry camp and only use the inverter occasionally? The better alternative for me is to load support the trailer battery when under heavy inverter load with my truck idling. For intermittent use that lasts just a few minutes, such as running the toaster or coffee maker, that makes sense but to let the truck idle all night long just so it can load support something like a furnace or fans makes no sense at all. Neither does expecting the truck's electrical system to load support such a huge load as that created by a microwave oven ... but for reasonable loads it works just fine.
