RE: 12.00 Volts to 10.00 Volts LED Bucker

If you roll your own switching converter, you can dial it in to your application. I used the software from http://www.ti.com/ww/en/simple_switcher/index.html to make my low loss fan control.

RE: truck reverse lights always on when truck camper plugged in

Converter? Inverter? The systems are DC, so no inverter is required. Sometimes a converter is needed to combine a separate amber turn signal with the brake light to get the proper indication, but most of our US made trucks are not equipped with separate turn indicators. What are you driving? One trick sometimes used for trailering is to let the hitch coupler provide the negative return path. This is a bad idea in the first place, but is guaranteed not to work with a camper that doesn't connect to the coupler. Weird behaviors result as the current attempts to return through various other lamp filaments.

RE: 12.00 Volts to 10.00 Volts LED Bucker

We like LEDs because they save energy, but any device you add will reduce the overall efficiency. The added diodes will dissipate (waste) power by the product of the current through them by the voltage dropped across them. Drop two volts with diodes to 10V at 10 W, and I calculate 2 W dissipated by those diodes. Switching converters get around this little detail by switching quickly from off (little current) to on (little voltage drop). Still some loss of course, but I expect a good quality switching converter would provide the best efficiency.

RE: Charging the camper batteries with the truck motor

Yes, there is a fairly simple way around this without rewiring everything. You can fool your voltage regulator by using the diode method I linked to.

RE: Sleeping cool without AC

Thanks for all the replies; definitely getting some good ideas here. I didn't mention our two canine companions on the camper floor. Closing some of the windows might help us, but at least we humans can sweat. Still may be room to experiment here, although getting out of bed to perform those experiments doesn't help the situation. I know the gel toppers get great average reviews, but I always check the 1 and 2 star horror stories too. Like KansasKen, many claim the gel pads make them hotter. The wool fleece looks intriguing, as does the Sirocco fan. Looks like it's time to break out the credit card. Thanks again all.

Sleeping cool without AC

Our past weekend trip in Central Oregon left my wife asking for AC, something I dread. We've avoided hookups and generators for 15 years, and I'm not very eager to start now. Nearly naked on top of the sleeping bags, windows open, FF on; we'd sweat until temperatures finally dropped in the morning. I note that there are several mattress toppers on the market that claim to have cooling properties. Can anyone vouch for any of them? We've been using a dense memory foam topper that makes our bed nearly as comfortable as our Tempurpedic at home. Maybe this is part of the problem; but with a sheet and two layers of sleeping bag on top? Any suggestions for staying cool and AC free? Thanks.

RE: license plate

The argument about pulling trailers is a weak one as the trailer has a lic. plate that allows for identification. Which is the real intent of the law we are discussing. Law enforcement has to be able to identify you as you are on the road. I commonly tow an un-tagged utility trailer. Where I live, plates are not needed on trailers under 1800 lbs. I remain legally unidentifiable from the rear, and the nice short tongue keeps identification from the side pretty questionable as well. I see no weakness in the trailer argument. (I suppose some of you will recommend counterfeiting the truck plate to attach to the trailer, or moving the truck plate to the trailer when towing:))

RE: Which Timberens?

I have the standard style also. Due to the mounting location inboard of the springs, they increased sway when engaged. I corrected this by using the bump stops they replaced on the overloads in addition to a pair Energy Suspension stops. Stable Loads are now an option.

RE: What size of a tv is in your truck camper?

I'm a TV addict, but when in the camper I go cold turkey. I'm with kohldad, 0".

RE: Bike Rack for Front Hitch....Experiences?

Pulling a boat? One year I mounted the Yakima bars on the boat so we could carry four adult bikes and still be safe driving at night.

RE: No RV parking signs

I figure it's a truck when only non-RV parking spaces are available, and it's an RV when the RV only spaces are handy. Haven't been cited yet.

RE: converters bad idea?

The link and diagram are a very close match to the OEM Magnetek that came with my camper. Like the author, I was surprised by the very bad idea at play. At work I use stationary DC systems with float chargers that function to keep the batteries charged while supplying DC loads. When the AC source is removed, the DC load is uninterrupted as the battery takes over. With my Magnetek, the loads all blinked as the relay transferred. Further investigation revealed the very large AC ripple present on the DC load bus because the filtering ability of the battery was isolated away on the wrong side of the relay. Add in the lossy power resistor on the output, and I saw good reason to upgrade. Maybe the article is about last century stuff, but a lot of it is still out there. Even in the last century, this was a bad idea.

RE: Bike Rack for Front Hitch....Experiences?

The headlights reflecting off the rims is blinding. A 10 minute nighttime test drive was enough to convince me this was a very unsafe idea, and went for a utility trailer instead.

RE: Front Rubber Stoppers

Like the link says, you should lift the ( fill in the blank ) first when unloading. Takes the moment ( movement? ) off the bumpers. Thanks. I inserted the missing word. Moment was not a mis-spelling, though.

RE: Will we need a bigger truck jack?

I was under the impression the jack supplied with the truck could lift the truck at it's rated GVWR. Is that not true? (I understand the concern if your truck and camper are over the GVWR but if they are under?) Me too. A camper is easy to deal with, but does the maker expect you to unload a bed of gravel to change a tire?

Happijac instructions Like the link says, you should lift the front first when unloading. Takes the moment off the bumpers.

RE: Sway bars versus RAS versus SS…which one did you choose/why?

To be clear-want to correct for sway/lean/roll/tracking. Tx, Bill The RAS and SS simply tighten your suspension. This may have an indirect efect on sway/lean/roll, but the anti-sway bar transfers motion from one side to the other and will do so regardless of how soft the suspension is. Anti-sway bars would be the first thing I'd look at to deal with the sway/lean/roll caused by a camper.
