Welcome to the club, from Southeastern Connecticut!
Part 1:
In my humble opinion,(IMHO) the set-up that you describe is barely marginal, at best, even to just charge the batteries. The voltage drop over that distance is not good for your inverter/converter, and could cook your 120v appliances. If that is the length that you need to go, don't even plug in to the camper, just put a battery charger on the extension cord, and go straight to battery, and settle for 12v.
Part 2:
As already stated, any reliable 12v power source will run your 12v lights, pumps, furnace, etc... and yes... a car with jumper cables will do the job, but would not be my first choice.
My advice, if this is an ongoing situation, would be to trench out to your site, and run a dedicated permanent (code compliant / GFI) power source. If you're not comfortable with 120v, hire an electrician. or trust a friend. The money you'll spend, is cheaper than the damage you'll do with undervoltage.
Good Luck,
