If so why do you need a invertor?
You do have a 5,500 watt generator for power dry camping.
1st you have to add up your wattage you have for your 120 volt items.
You won't have all running at the same time so this number just give you some idea what you have.
Then you have to look at the size and amperage of your batteries inthe coach.
The ones you get all depend onyour model and I can tell you what they will be other than two 12 volt batteries hooked up in parrellel.
Then you have to ask yourself when would I use this invertor?
Will it be for short dry camping and I will only use the TV at night for a few hours or will it be more?
Bottom line is that a minimum should be 1000 watt and a max would be 2000 watt.
The other question is doesn't your rig come with a generator?

Questions and more questions...
I'm sure you will recieve more opinions. No rush and wit until your coach is delivered and see what it has.
Can't tell you if you need a cover but they usually only last a year or two before they need to be replaced. Expensive.
DO NOT waste your money for a dealers extended warranty.
If you use your rig enough in the first year you will find out what needs to be repaired and replaced under the FR 1 year .
Also Ford covers the chassis, engine and drive train for 36 months or 36,000 miles. Don't let the dealer scare you in buying a warranty for say 2 years which really is only for 1 year as FR covers the first anyway.
Put $3,000 in a special bank account and don't touch it an dthat will be your warranty.
Good luck. Now the waiting begins.
