Purchased my 2003 R_Vision Condor back in Nov. and have had problems with fuel delivery. This unit only has 6500 miles so i'm thinking it obviously sat for long periods of time and has developed some "trash" in the tank that is clogging the fuel pump pick-up in the tank.It has fresh gas, two containers of "heet" added (for moisture)and a fresh fuel filter but continues to sputter, pop and die on occasion when coming to a stop. My question is: Does anyone have experience in draining and cleaning the tank, short of pulling the whole unit, which I've been told is going to be somewhat expensive? My shop tried to run a hose down to siphon but was unsuccessful. Hard to believe that there's no way of replacing the fuel pump or cleaning the tank short of pulling the whole unit.
Perhaps someone has experienced these same symptoms and it wasn't the gas at all?
Any input or ideas would be appreciated!
I think you need to be using it more like a daily driver as in going shopping at WM, going out to eat, etc locally. We did this to help build driving skills in tight places and it worked the trash to the fuel filter over time
A gallon of Sea Foam to a full tank of gas but no more than two gallons would be what I would be doing to help break up any clumping around the fuel intake plus a 1:500 ratio of WM TCW3 spec outboard marine oil for a lube for the fuel pump.
This is not just some wild suggestion but exactly what I have done with the MH and the F700 truck that had set a lot.
After you burn your second tank and maybe replaced a few fuel filters you may be good to go. Maybe you can run to places within 50 miles of were you live. At the time the kids were doing a lot of regional swim meets so we ran up some miles doing that.
Do you have the chassis with the brake recall? You may find other low usage issues when you start making a lot of 100+ miles run around the area. Check your tires for serious cracking but I expect your tires may be fine for local runs unless the cracking is really deep looking.
If you look underneath at the area where the tank fill hose connects to the tank, you should be able to remove the rubber connecting hose to the tank and then stick a hose in the tank to siphon to a near empty state. Awkward but doable. I think that you will find that on a MH you will actually have to drop the tank to access the fuel pump.
On our fleet of Workhorse step vans, there was a plate on the floor above the tank to allow access to the fuel pump. Its a long shot, but you may have one in your MH also, doubtful but worth a peek.
BTw: The fuel pump on the Workhorse is prone to overheating if you consistently run the tank to a low state. Had to replace a bunch of them until we made sure that the drivers never allowed the tanks to run below a quarter.

There have been a number of instances where these engines will have a cam or crank position sensor not operate up to spec and create a situation very similar to yours. Sometimes they set a code, trigger the CK Engine light and sometimes they do not. Before you pull the tank take it to a reputable GM facility and have them look at it. There are many instances where the dealer is aware of issues like this and the "great" independent repair facility is not. This type of situation is where your "great" independent repair facility ends up being considered absolutely worthless because "they are idiots" and can't fix the problem.
Have the same coach and you have to take down the tank to pull the fuel pump(had it done last summer). It's possible that you will need to replace the external filter again if the new one caught more junk. If you can get to it, it's worth checking. Rather than a GM dealer I would recommend a Workhorse dealer since they are the provider.
Final thought, go to Workhorse.com and check out the manual/specs they provide for your engine and chassis.
