  1. Thanks to all for the suggestions! Much appreciated. We have hull #747 so we probably have the same pump as #688. We have cleaned out the filter and checked another supply line for debris but that is it so far. No problems at all on city water, and the low pressure problem we have developed slowly during a 2 month trip last summer. The pressure goes down considerably once the accumulator pressure is depleted, at both the kitchen and bathroom sink. Have spoken to the Oliver service folks about this and they asked us to send a video, but by the time we got the request from Oliver the trailer was already empty and in storage. I was thinking that a spare was a good idea in any case, even if we get the current pump back to its original state.
  2. Any one have a suggestion on a spare water pump for an LE II? The pressure in ours has dropped and I think there may be plastic debris in it. Thought it might be a good idea to carry a spare.
  3. Thanks all for this very illuminating thread. Before our Oliver we had a class B with a second alternator, 300 watts of solar and 400 amp hours of lithium battery. Since we were driving nearly every day we never paid any attention to energy use. Th class b had a compressor frig that worked very well- we never thought about its energy consumption. This new 3 way has been a bit of a pain! It struggles to get and stay cold and has condensation issues. We have 340 watts of solar, and 390 amp hours of lithium in the Oliver and no battery charging when we drive. From everything I am reading, setting up the system to recharge with my tow vehicle (Ram 1500 etorque) would not help all that much (a topic for another thread). Regarding energy consumption/ replacement, All the figures people are quoting seem about right given our 2 weeks in the trailer post-pickup last February. If we stayed away from the big energy hogs (instant pot, induction cook top, etc) when boondocking we were gaining about 70 amp hours per day from solar and using about the same amount. That is in the winter sun in Florida. We do carry a 3400 watt dual fuel generator so we always have that back up. Sure wish Oliver had told be they had the 640 amp hour lithium’s on the horizon. I would have jumped on that. On the positive side, Lithionics is in Clearwater Florida about an hour from me. They may be willing to install the bigger lithium’s which seem to fit in the battery compartment of the Ollie. Yesterday, Oliver told me that wanted $12,000 to do the switch!!! Obviously they do not want to do the work.
  4. Has anyone installed a compressor refrigerator in their Ollie? We have lithium batteries so can’t use the tow vehicle to run the refrigerator while we tow. The 15 amp draw of the 3 way is a bummer! Also, we camp in the mountains above 5500 so the efficiency of the 3 way will be an issue. I also would like to avoid the low outside temperature limitations of the 3 way. Is there an AC/DC compressor model that would fit in the Ollie’s refrigerator space? Thanks for the input! Bob
  5. Bought a torque wrench today in anticipation of picking up our trailer in 3 weeks. What size are the lug nuts on the trailer wheels? Any suggestions on a good set of lug nut sockets? Thanks!
  6. Has anyone used a gps tracking system to keep tabs on your trailer? We will be storing our trailer off site and are thinking about starting a service as part of our security strategy.
  7. We Nothing from Oliver, but I was asking about the lithium system and not this issue per se. The folks at Lifeblue have been very responsive. The best way to communicate seems to be to email them at sales@lifebluebattery.com
  8. I called Oliver asking about the interaction between the tow vehicle and lithium system and they sent me to Lifeblue for answers. That is a bit off putting! The folks at Lifeblue were much more helpful. They offered to send a circuit diagram if I sent them an email. Here is their reply to my request. LiFeBlue Battery can be charged from any tow vehicle. All alternators are compatible with LiFeBlue Battery. No special DC converters, controllers or regulators are needed. This is one of the many benefits of LiFeBlue Battery. Our BMS was special designed for RV and marine market and can accept charge from many sources simultaneously, both low and high current. Our battery will charge as long as you can deliver a voltage of about 13.6 or higher to the battery. Because of the very small wire size and long wire run to the 7 pin connector, it is not likely that much if any current will flow. For this reason, we highly recommend the installation of an auxiliary charge circuit like the one in the attached diagram. Your alternator will become a very valuable power source that can even replace the need for a gas generator saving cost, weight, space and the need to carry gasoline. You can idle your tow vehicle engine and run heavy loads. Some even run the air conditioner from their inverter. When designing the auxiliary circuit, the less voltage drop you have, the higher the current you can deliver. Shorter distance and larger conductors decrease voltage drop. You can easily charge at 80 Amps or more with most alternators using this method. Here is the diagram. Alternator Charge Circuit.pdf
  9. Here is a description of the etorque system on the Ram 1500. My question is can the 48volt lithium battery in the tow vehicle be used to charge the lithium batteries in the Oliver without damaging the trailer or truck? And who could do the work necessary to set up the electronics? The eTorque system includes a battery pack with 12 pouch-format nickel manganese cobalt lithium-ion cells from LG Chem, supplied by the battery giant’s Holland, Michigan, facility (which also supplies the Chevy Bolt EV, Volt, and others). The modular power-pack unit, from Continental, includes an inverter and DC-DC converter.
  10. Folks- we are picking up our Oliver in February and it will have the new lithium batteries. We will be towing it with a 2021 Ram 1500 5.7l hemi with etorque. As best as I can tell from the folks at Oliver, the Oliver Lithium system wIll not be charged by the tow vehicle electrical system, but it seems that it could be. Anyone know anything about this? We previously owned a Roadtrek class b with lithium and a second alternator kept the lithium batteries charged very nicely.
