RE: Adding second A/C to travel trailer - which one?
I just completed the mod you are describing. I went with the Mach 3, though. Since I was going to run a separate wire to connect to the pedestal then as long as it was under 20AMPs, I was OK. Got the Mach 3 for a considerably lower price. It's not ducted but I did tie it into my thermostat for control. Turned out great and didn't have to upgrade to 50 AMPs.
Howdy,
I am thinking of doing this exact mod, only buying the parts and having someone else better qualified than me do the installation. I have a couple of questions if you don't mind:
1. How easy/difficult was it to tie this into your existing thermostat?
2. Do you have any pictures that you can share of your connection on the outside of your TT? I have a filon-sided TT and am wondering where to have the connection box placed.
Thanks,
Mike
To tie into the existing thermostat only required me to get a run of thermostat wire from the second a/c to the first a/c control panel. This was accomplished thru the ductwork and getting the appropriate control for the new a/c.
I have pictures but am unsure about posting to this site. I don't use third party picture accounts. But the picture above is the type of connector I used. I used a hole saw to drill thru the filon into the lower portion of a cabinmet that my 30 connection is located. I installed a 2 slot breaker box and installed a breaker into it for the a/c circuit.
I then managed the wire from the a/c to the portion of the cabinet where the breaker box was located. I ran the wire in a automobile type plastic conduit to protect the wire in the front corner inside the cabinet.
After I was bale to gather all my supplies my son assisted me in getting the unit to the roof and I had the job completed within about 5 hours.
On the first very hot day I started both systems and set the thermostat for 65*. The outdoor temperature went up to 105* and I was in direct sunlight. The temperature inside never rose above 65* and would actually cycle off.
Hope this helps. If you PM me your e-mail address I will attempt to find the pictures and send them to you.

RE: Adding an additional vent to A/C unit?
Most ceiling units that are made non-ducted will not have the capability to include the vent type that you have selected. You would have to switch to a ducted type ceiling assembly and would need ductwork.
Sorry I can't give you any better information.

RE: Why does my AC fan run with the furnace running too?
If you have it wired the way the diagram is layed out and set-up according to the gas and a/c instruction in the book, then you probably have a bad thermostat or two wires touching. One way to tell would be to disconnect the wire from the "G" terminal and try again. If the fan continues to run look at the wires to make sure nothing is touching and if it stops get a new thermostat.
I have used a digital thermostat in both of my rigs but do not use the toggle switch. I wire high speed into "Y" with the compressor and put low on the "G" terminal. This runs the fan in low speed when the "fan" button is turned on and tuns it in high whenever the a/c is on.

RE: Why does my AC fan run with the furnace running too?
It may be that you have it set up incorrectly. You DO NOT need a relay, that's all a thermostat is, is multiple small relays. Check and follow the manual set-up procedure correctly.
Make sure the switch on the back of the thermostat is set on "G" not "E" first, the system type is set to gas and a/c, not heat pump, and that the heating cycles per hour are set to 5, and cooling cycles per hour to 3. I suspect the switch is currently set on "E". This energizes the fan relay each time the thermostat calls for heat or cool.

RE: Intermittent AC problem
The humming noise might be your converter or converter fan. It sounds like your converter may be overheating and shutting down causing a loss on the 12 volt side. Check to make sure your fan is in fact running. Thats where I would start.

RE: Ever heard a moaning metal sound from your WD bars?
Mine used to. I use a light misting of WD-40 at the cam part (Reese Dual Cam) and at the head where they mount. Problem solved and have had no adverse effects. This is the final part of my hook-up procedure now.

RE: Tire Recommendation
We just bought a 2007 Wildcat 30LSBS and are planning a long trip this winter and we probably should replace the tires. It currently has Transmaster ST235/80R16, 5 plies, Load "D" with a max load of 3250.
I'm not sure how to decipher the year made, DOT 8HUN 3505. I thought the last 4 digits indicated the week and year, but it doesn't make sense.
So, what would be a good tire to get without blowing up our bank account?
Also, does Les Schwab carry good brands of trailer tires?
Thanks
Load Range D = 8 ply. Every letter designation indicates two additional plies.
E = 10 etc.

RE: chevy hitch receiver
We have a 2009 1/2 gmc with tow haul. We are looking at getting a 3/4 ton chevy with tow haul.
We have a travel trailer and the hitch setup for the 1/2 ton already.
Someone told us that the 3/4 receiver would be larger in diameter than our 1/2 ton is this true?
And if so is there a shim or something I can use so our current hitch setup works on the 3/4 ton truck.
The truck should come with a reducer if it has a V5 rated hitch. Be prepared to completely re-setup your hitch though. The difference in height of the vehicle will need to be compensated for. In my case I had to purchase another shank to get a level load. (I use a Reese Straight Line with Dual Cam sway control) Without the new shank I was approx. 2" higher at the hitch than I should have been and it created a great deal of bounce while travelling. With the new shank the tow is unbelievably smooth.

RE: Added Reflextix to Roof A/C and Exterior Vent covers
As the old sayings go "each to his own" or "whatever floats your boat". I doubt you hurt anything, but also doubt you helped anything since as far as the A/C goes the cover is already white and the condensor fan will keep a lot of air moving inside the A/C cover so there should be no heat build up.
As far as the Max Air vent covers go, I would think that would really darken things up and again any heat is already outside the trailer and should have no effect on the interior of the trailer heat/cool wise.
At least IMHO seems like a lot of work for what I would think would be marginal at best improvements if any.

RE: A/C Sportatic issues
if you have Dometic brand....quite possible a board issue, or connection between board and T stat or even a T stat and not the compressor
You need to check the amp draw with compressor running

RE: AC no blow
Could have just developed a "stuck" point or could be a weak or bad capacitor. If you can shut it down and it restarts later, probably just "stuck".

RE: Outdoor kitchen fridge, what a mess!!
Does the outdoor fridges usually operate on an inverter or are they 12V units? I assume they aren't the traditional absorption type?
Ours is a standard 110V small refer. No cooling while traveling. Only after arrival and connection to shore power.

RE: 50 Amps or stay with 30 amps and 2nd cord for 2nd ac
The cord has to be replaced if I go to 50 amps. I am just wondering from a standpoint of being able to hookup to a pedestal which route would be better. A 30 amp and a 20 amp cord or one 50 amp.
Has anyone ever made a 50 amp to 30 and 20 adapter?
I am adding a 2nd ac so I need the extra power.
I recently added a second AC to my Rockwood. I added a separate 20 amp circuit that was protected by it's own breaker. I now have a 30 amp connection and a 20 amp connection on the outside of my trailer. When I get to the campground I just plug into both at the pedestal.
Conntek makes an adapter that will plug into a 50 amp plug and has a 30 and 20 amp plug coming out. (EXPENSIVE, though) $130+. I did purchase it though because it was still less costly than converting to 50 within the trailer and it works great. I actually have both my ac's working off the single thermostat. If I don't have the second a/c plugged in, it just doesn't work.

RE: roof a/c unit install
Remove the four phillip head screws and remove the bottom portion of the vent. The screen and everything above will stay in place. You should be able to see the wire just inside the ceiling cavity.

I believe 5600 or 5800 watts are the heaters available. Check the link above.

RE: grey water over flow inside camper
MOST Forest River models use Styrofoam insulation in the belly and getting wet will not damage it. I'd dry everything out with fans on the interior of the RV. Water won't damage the Styrofoam nor will it harm the coroplast covering but the underside of the floor CAN be damaged if not dried.
X2 - Use a dehumidifier for several days and you may be OK.

RE: Temps up, how cool can you get inside?
I just completed a second AC install at the beginning of the season and had been waiting for an extremely hot day to check it's performance. Yesterday in direct sun it was 102* and I had had my thermostat set on 60* since early morning at which time it would satisfy. Once it reached 100* the unit would not satisfy and the temperature rose inside after that point. It never exceeded 62*. So I can cool 40* below outdoor ambient in the direct sun. Now I need to do the same test in the shade.
