My 2010 Roadtrek 190 batteries both coach and chassis both go dead in a week to 10 days. I have replaced all the batteries and make sure when I park the unit that the invertor and chassis battery switch are both off. Is this a common fault with the Roadtrek 190? Our dealer support in my area is very poor and when I called Roadtrek directly asking for information about the system so I could maybe find the problem all I got was the answer that I must have modified the system as this never happens to their units. Does anyone have any ideas so how I can locate and solve the problem. problem

I dont have an RT, but a conversion RVan. I have had persistent leakage ever since I had an alarm system installed. Various mechanics have found/fixed problems, grounds and bad wires (my van is old) but I finally had a "priority start" installed and carry a "jump start" just to be sure. Are there fuses for different parts/items/areas in the RT? Pulling a fuse and checking the battery charge after a day might at least narrow down the culprit. Most times a nail or a screw nicks a wire and that is where the leak is occurring. It is just really bad luck.

Often times things like the propane detector are not turned off by a master disconnect.

The 2008 Chevy chassis has a history of starter battery discharge, but better on later and earlier years. Even so, it shouldn't kill the house batteries at the same time. You might want to see if the separator has failed and is locked in all the time. It would pull about 1.5 amps and from both batteries, so it could do the deed in 7 to 10 days.

You are not the only one this has happened to. I know a few other 190 owners who experience this - and apparently the problem with the chassis battery is with Chevy. One solution is to install a battery shut off switch on the engine battery. My 2011 190 has not had this problem but I do plug in to charge at the end of every month and then also run the generator for two hours in the middle of every month which will also give the batteries a boost charge as I was seeing my coach batteries going low if I did not do this. Always turn off the battery disconnect switch inside the Roadtrek when not traveling. There is enough connected to the 12 v system that draws power with that switch on that it will run down your coach batteries quickly (but not the engine battery).

We dry camped for 3 days this summer and the chassis battery wouldn't start the engine at 9+ volts. The separator was not wired to allow coach batteries to assist in starting. On returning home, we had the separator checked - not charging the coach batteries. Probably discharging the chassis battery. New separator installed and wired for manual assist from coach batteries. Sorry to hear from Booster that we have an on going problem. However, we will conduct an experiment by not connecting shore power to the RV and see what happens.
