rookieRV is concerned about the converter, not inverter. He is planning on a Progressive Dynamics converter.
Here is an article by K7TTY about RF in an RVj

That’s right, John, a CONverter, not INverter. The article by K7TTY was informative. However, the Parallax unit 7300 (gee,
I used to have a Parallax ;D) that is highly praised there is of a “power center” design, not of a “sealed appliance box” design that I”m replacing (for simplicity? or convenience sake).
Quoting K7TTY:
“They [PD] recommend that :
Make sure your converter is not near or around antenna wires.
Some customers have found that turning the converter 90 degrees helps. :
Some have gone as far as to build a cage over the unit to catch RF. [gee, an idea of mine, too] :
Really the only sure fire cure at this time is to disconnect the converter from AC and run on just battery power when using your radio and connect to AC when done.”
Buuut, K7TTY gives much praise for Parallax [at the very least,
a particular model of Parallax, the 7300 series “power center” design]. While he additionally gives praise to Parallax for UL type acceptance (regarding the issue of rfi...apperantly, the other brands (PD in particular) don’t enjoy this acceptance), I have perused through the newer Parallax ‘appliance’ models (4445)... while they will absolutely positively say that they
could function w/o any batts [like the Iota]8), they seem uncertain as to describe themselves ‘multi-stage, smart chargers’ or not :-\. The only word that they seem to take time to come and patently mention outright is, ‘boost’. Wait a minute, another site
does say “The 4435 Deckmount Converter by Parallax Power Supply is a
three current stage [not 2 or 4]...” While the new Parallax models
do have batt temp gizmos, they don’t
appear to have
any ‘charge state/wizard/dumb indicator’-like options.
