RE: A-Liner Sway
Sway controls are a poor band aid fix for lack of proper tongue weight. Trailers need a minimum of 10% of total weight on the tongue to track properly.
RE: AC duct leaking
Most ceiling registers used in RVs have a louvered section that will come out. Once that is removed you will be able to see where the assembly attaches to the duct work. That is where it is often not sealed well.
RE: AC duct leaking
Most likely the ducts were not sealed properly at the A/C unit and/or the various registers. To check the unit connections you need to drop the ceiling assy. of the unit. To check the registers; generally the louvered portion pops out. Any gaps in the connections can be sealed with metallic duct tape available at HVAC or plumbing supply houses.
RE: Dometic AC freezing up
If you are getting icing you likely have an an airflow problem. Is evap. coil clean? Filter clean? Duct work clear and ALL registers open? Ceiling assembly installed and sealed correctly?
RE: Quadrants, rather than one big cross country trip?
Your quadrant plan is good and I would figure more the 6 to 8 week time frame. In some instances you may even cover a smaller area. As far as going over old areas. It will happen over the years; but by using different routes thru them you will see different things. Keep reservations to a minimum so you have a more flexible schedule.
RE: 12 volt issue?
Check your fuse panel and confirm if they are all on the same circuit. It may have an auto reset breaker instead of a fuse. They look similar at first glance; but a fuse will have a visible fusible link.
RE: Hot Air Blowing Out From Behind Out Fridge
This is normal as it also is for when a residential refrigerator is used. That is a downside of using this type of refrigerator. Heat load wise you now have the equivalent of an extra person in the RV all the time.
RE: Soft Start question
Are you taking the readings in the RV or at the service connection? A voltage drop is normal when operating a high current device like an A/C. How much it drops will be affected by the quality of connections (ie plug & receptacle), voltage, and wire size. A start assist device only reduces the the current spike of the compressor start.
RE: Why Is My Air Conditioner Squawking?
Sounds like bad bearings on the fan motor. Unit seems to be a bit new for that; however, if it was used in very dusty conditions it is possible.
RE: So tell me about your perfect couples travel trailer
I have found that a rear living floor plan works good for your described situation. Since you are looking at used; probably more important than brand is age and current condition. I would avoid anything with foam core floor construction.
RE: 2 outlets in GFCI path not working
Sounds like there is a broken connection to the outlets that aren't working. Most likely at at the last outlet in the chain that is working or the first one that is not working.
RE: Water Heater with Electric Heating Option?
You likely will not find a manual specific to a your trailer as those supplied by the manufacturer are normally general in nature. You should be able to find manuals for the various appliances on line using make and model number.
RE: How to install stuff on walls
If you are replacing shades you can likely fasten the blinds in the same location with screws. Windows normally have a frame around the perimeter that you can screw into.
RE: Vent fan upgrades
Easiest to install are the Vortex as they will go into the existing vent. The Maxx Air are a little nicer and slightly quieter; however they require replacing the entire vent assy.
RE: New Orleans
Unless you are into just urban activities; why restrict yourself to just New Orleans. As you go west cuisine changes from Creole to Cajun and landscape from swamp to prairie. The time you picked is mid summer so it will be hot and humid, but there is much to see. It all depends on your interests.
