Hi Steve,
I'm not an expert on this, so I could be wrong but I think you've received some bad advice. I'm pretty sure removing the regulator creates a safety issue. RVIA docs say: "If debris obstructs the working mechanism of the regulator, high-pressure LP gas may pass directly into your appliances. Both possibilities create substantial safety problems." I'm pretty sure removing the regulator would be equivalent to it having an obstructed mechanism that passes LP at tank pressure, instead of at reduced pressure.
Another way to look at this is manufacturing cost. If the regulator was not really needed, do you think that ANY RV manufacturer would waste money putting one there?
Until you can replace the regulator, I'd suggest switching tanks manually, even though you'll have to lug them around.
