Purchased a pre-owned 5th wheel and in looking around at the electrical, I noticed the 12 volt converter was replaced and had a small telephone like connector. Looked into the brand name and went to Iota's website.
A little research later, I find that my Iota DLS-55 was capable of using an external upgraded brain. It can be even smarter than it already is! Now it's a 4 level charger. Found one online and it works great inline with my Trimetric 2030-RV.
Quite happy so far. After just spending over $500 on batteries, it's good to know the charging is more controlled and will help preserve my battery investment. I understand they're both covered by a 2 year warranty, so a piece of mind is included too.
