[Elecraft] Mobile from 117 VAC

Previous threads provided a great deal of info about arranging automobile electrical systems to power HF rigs.  But as I recall, it all focused on using the battery / alternator supply for the 13 VDC.  Though I wanted to go mobile and still do, for a number of reasons I could not configure my car to do it properly.  I am now thinking of buying a new SUV which has 117 VAC outlets in its rear cargo space.  That makes me wonder – could I just use an ordinary 117 VAC to 13 VDC power supply, exactly as I do at home, just plug it in and – staying within the car’s rated current draw – operate without worrying about where the ground goes vis-à-vis the battery, what-all needs to be bonded with what-all-else, how everything needs to be mummified in ferrite, etc?  Or are the problems all the same even though different?  My objective is simple.  I want to be able to drive to a rare county, set up my buddipole in a parking lot, and use either a XX3/KXPA or a K2/100 to knock out some CW QSOs.  I do NOT want to take an electric drill or a rivet gun to a new car.

Has anyone gone mobile using a car’s 117 VAC outlets?  Any thoughts to share?  Any thoughts from anyone who for any reason hasn’t done it?

Tnx.
