Will definitely look onto the Trik-L-Start. It will be nice to have both batteries charge off shore power.

Keep an eye on your batteries when being charged by the converter/charger. Yours Is likely a 2 stage. Charges fast to bring the batteries up, then slows down to a still too fast mode useful for boiling all the water out of your batteries.

Hi! New to the list and late to this party but . . .

I live in a 1987 Rockwood built on a 1986 P30 Chassis.

Last things first, my original power converter was a simple harmonically regulated transformer-rectifier that did little to charge the house batteries. That was quickly fixed with a 3-stage unit.

The fuel system. Being an '86 chassis I have the in-tank fuel pump and the engine driven mechanical pump. It very nice to turn the key and hear the carb fill up with fuel before I start the engine. That said, the fuel line from the tank to the front pump should be 1/2" steel. Otherwise the rubber line tends to close up under vacuum. There is a vapor return line from the mechanical pump to the tank, a vent line to the charcoal canister and a line for the generator. My generator line goes to the bottom of the tank.

A low pressure 4# electric pump at the tank is a good thing in my mind just keep in mind that the 454 drinks 25 GPH at WOT.

Appreciate the info, late or not.

On my tank, all 4 lines come out of the tank rubber. The line to the mechanical fuel pump and the vapor return line change over to metal at the rear axle. The vent line is not going to anything at the moment and I didn't see a charcoal canister for it while I was under there (could be hidden somewhere though). Where's your canister located?

They are located on the passenger side. There is one mounted to the frame that holds the radiator in place and a second one higher up mounted on the radiator support-brace. I didn't find the second one until I took the radiator out for repair.
