Your dealer is probably referring to the
Rieco Titan conversion kit for Rieco and Atwood manual jacks. If my camper had manual jacks I would be converting them. Years of abuse have left me with shoulder problems that make manual cranking, even with a cordless drill, painful.
Since joining this forum, I've known of 4-5 members that have used this kit, and have not heard a negative report from any of them. The most recent one was member vik1 in France. Although his jacks were Rieco mechanicals, the conversion kit is the same one used on the Atwoods. (BTW-Happijac also makes a conversion kit, but it's for their jacks only). Another member 7-8 years ago was Lance835, who also used this kit. I remember him because he sent me the parts he removed from his jacks so I could repair my old manual crank jacks on the Jayco TC I owned at the time (Atwood doesn't sell repair parts for their jacks).
My first two truck campers had manual jacks, but I consider remote controlled electric jacks that can be operated individually or all at the same time a very worthwhile feature these days.
