Yes, I had a brake line start leaking on my '06 Sun Voyager. In my case it sprayed directly on the exhaust and made a lot of smoke. A shop near me was able to replace the brake line tubing with generic line. It ran down the cross member from the left to the front right brake. Cost was about $200 if I remember correctly.
I had 2-12v batts for the house, but I replace them with 2-6v golfcart batteries from Sams. That's worked rather well for me.
Also check the hydraulic oil reservoir. Maybe it's low.
