DOES NOT START/RUN

Test drove it upon first putting up listing, repaired the cabin a/c, drove it to the airport and back, put 1/2 tank of diesel in it, parked it, next day no start. Worked on it when I could, not a diesel .mechanic. Replaced both fuel filters, fuel pump, oil filter and both cab batteries.

2004 Diesel 6.0 liter Born Free RV, 26 feet long. It has the rear side bed measures 75 x 50 inches. Working generator (propane model 3600LPV), refrigerator, hot water heater, combo microwave oven. Sleep sofa and two side captain chairs, in leather. Push button outdoor awning, laminate flooring, steering stabilizer, outside shower. Sleeps 4. Tows our Jeep Wrangler with ease. We have the original curtains. Includes an additional outdoor step, two awning stabilizers, leveling blocks, and a mattress topper. One photo of the bed has the topper and the other does not because I took off the cover to wash it. Here are some specs from the owner's manual: 26'7" bumper to bumper length, height 118", Body width 95 1/2 ", Interior height 76", Gross weight 14,050, 55 gallon diesel tank, 35 gallon fresh water tank, 6 gallon water heater, 23.2 gal usable LPG @ 80%, 35 gallon fresh and gray water tanks, 21 gallon black tank. Born Free RVs are known for their superior craftmanship, this is our second Born Free and we have been really happy with both. All cabinets are solid wood, not the particle board junk in most other rvs. These vehicles are also equipped with roll cages in the back to protect backseat passengers. It has the 6.0 liter Diesel engine. We estimate we get about 10-12 mpg when we tow. We have never kept careful track as there isn't much you can do about rv's being fuel hogs. The tires are in good shape. The tires were manufactured in 2017 and they are heavy duty truck tires, not the semi truck type. The roof is in decent shape and does not leak. If we were keeping this unit we would reseal the roof within the next couple of years. The nice thing about this RV is that it will fit in a normal parking space if there is grass behind the space for the overhang. It is super easy to drive. It is stored outside. We have had this RV for a little over 2 years and paid $36,000 for it so the price is firm. We thought we were downsizing but after camping with the grandkids we decided to keep our larger Tiffin. It did have some water damage from a bad seal on a window. We pulled out the window and resealed it. We also replaced trim. The unit does not leak now - it is bone dry. We have pictures of all of the work if you are interested in this RV. We also updated the interior lights, replaced the batteries, added a seat belt to the sofa (there are four factory installed seatbelts). We have the owner's manual. Really nice unit, located in Milford, Ohio. Serious inquiries only
