Sounds like the water has high iron content. All the chlorine does is mask the smell. Frankly I'd rather live with the smell than deal with the chlorine. I would suggest a 2 stage filter on the inlet to the RV. One stage a sacrificial particulate filter and the second stage a carbon filter. That should solve the problem. The carbon will remove the chlorine (provided it's actually chlorine and not chloramine - you need catalytic carbon for that).
Something like this:
2 stage filter
If you are drinking the water however, I would opt for an RO. Something small under the sink or a Burkey gravity fed RO.
The smell is generated by bacteria that thrive in iron-rich water. The chlorine kills the bacteria, which can, and usually does, eliminate the smell for a significant time. We have had wells with the problem for almost 35 years, and conventional filters are not useful for the sulfur smell, though they will stop the chlorine taste/smell. We have a green sand tank, followed by carbon for all indoor water and then RO after those for drinking water. We still need to shock the well with a couple of gallons of 12% bleach a couple of times a year to control the odor.
