RV's (motor homes and trailers) come in two kinds as related to this discussion.
And a 50 am rig is almost guaranteed to be just one of those.
Some older Trailers mostly (But I won't rule them out in a motor home) have some very nasty converters like the Magnetek 6300 which is well know to kill batteries by boiling them dry in as little as 1-3 weeks.
These will nearly always be 30 amp rigs (in fact the 6300 is designed for use in 30 amp rigs only)
Some have more modern converters like the parallex 7300, This unit is still a single stage converter but it has much better regulation so is less likely to kill your battery.... Or fully charge it for that matter.
Many have better converters, and here the list is too long to post.. I'm partial to the Progressive Dynamics Intella-Power 9200 line (or the 9100 with optional charge wizard) or any converter/distribution combo with the charge wizard.
These are top of the line3-stage converters with at least one special feature. (The Charge WIzred gives a quick shot of overcharge every 20 hours of float, This helps stir thins up in the battery (Equilize) but is not long enough to do serious damage)
The result.. When my Interstate U-2200's were new I had to add water every... Mother's Day. Yup, once a year. and to be honest I could have gone a month or two over (But mother's day was easier to remember as that is when I de-winterized) Today they drink a bit more but they are over 8 years old, that's like 80 in a human.
