If you have to convert -do not go electric and RV brakes are not the same as marine electric. What have you got now? Surge hydraulic? I saw a complete kit electro hydraulic the other day for 699 from etrailer-fabulous deal and not hard to do yourself. You will have nothing but trouble with marine electric-I had them for years and the maintenance is mind boggling!! some guys will tell you discs are the way to go and that could be true , and perhaps you should look at that option but that is still electro hydraulic-whether you go drum and perhaps keep a part of your existing system or disc-it is all electro hydraulic. Very reliable and reasonably trouble free. Whatever you do-do not try and save money and go straight electric as in an RV you will be converting within 2 years-guaranteed!!!
