Stage 1

• Shore power ONLY: roughly 4.5 hours from 0% with no loads on the system.
• Alternator charging ONLY: roughly 9 hours from 0% with no loads on the system.
• Solar charging ONLY: too many variables here to even begin to answer this.

Stage 2 and 3

• Shore power ONLY: roughly 4.5 or 6.5 hours from 0% with no loads on the system for stage 2 and 3 respectively.
• Alternator charging ONLY: In ideal conditions, it could be as fast as 1.25 or 2 hours respectively, but in reality it will be closer to 2 and 3 respectively. NOTE: if running the A/C or other high loads while charging, these numbers will be roughly doubled.
• Solar charging ONLY: too many variables here to even begin to answer this.

Solar will charge the batteries the same way that it did before. Keep in mind, when you have A LOT more capacity (larger battery bank), it will take solar A LOT longer to charge from 0 to 100%. The amount of electricity generated by solar doesn't change, but the overall time to fill the system will be much longer due to the larger battery bank.

A lot of variables here, but the calculation is roughly one hour of A/C per 100ah. This assumes worst case conditions defined as direct heat, daytime, no shade, etc. If it is a hot day, sunny, no window covers, and no other load on the electrical system, expect to get 4 or 6 hours out of most systems (depending on the number of batteries). This estimate also assumes 100% duty cycle of the compressor and fan running on high speed. If you are judicious with use and primarily use your A/C on low, at night when you are sleeping and there’s no sun beating down on the van, you could get as much as two to three hours of A/C per 100ah.

The batteries are inside the heated/cooled space in your van, which means as long as the van heat is on, battery temperature is not an issue in cold weather. If the batteries are below freezing while the vehicle sits, they cannot be charged. If the batteries are below -4 °F while the vehicle sits, they cannot be discharged. The batteries protect themselves and they cannot be damaged if you try to use them when they are below -4 °F. When they warm up, they will wake up and act normally. It is extremely difficult to get the inside of your van to -4 °F even if it is much colder outside. If the sun is shining on your van, it will be passively heated from that.

The chosen 3000w inverter is able to run the air conditioning with no soft start. Additionally, it can run the air conditioning while you use other high power appliances like the inductive cooktop. Finally, it has a built-in 100 amp DC battery charger for quickly charging your house battery bank when you are plugged into shore power.

How much do you want to read? In short, it is less than optimal for many reasons regardless of what you may be sold by others about heated batteries. Heated batteries, regardless of claims of being non-parasitic, all take energy to heat. That energy comes from charge sources (decreasing charge rate) or from external sources. The location of batteries under a stock 2020 or prior Revel is not conducive to rework such that a lithium system can perform optimally.

The Winnebago wiring is adequate to work, but is not optimal for an efficient lithium system that is installed in a central location under the bench seat. It is easier/cheaper/higher quality to remove the original wiring and start fresh.

Each component of the RoamRig system has a manufacturer warranty. The batteries have a lifetime warranty! The interconnecting components and installation will be warrantied by RoamRig (not the installation partner) for 1 year from the completion of the installation. For simple repairs or issues, RoamRig will provide direction for you so that you can quickly get back on the road, exploring the world!

Seat belts can stay. The OEM seat from Winnebago is not certified in any way, as there are no regulations in the US regarding passenger seating crash or pull tests.

We have a nationwide network of certified installers to install systems that you purchase for your van. Each of these installers is trusted with the reputation of RoamRig, and RoamRig will fully back their installation work. Each installer has done dozens of installations.

Yes! We do installs 5 days a week at the shop in CT. If you are there by 8am, you will be out by early evening. This is the ONLY shop in the country where same day installs are possible.

If you are buying a 2018-2020 system, please visit that product page for details, fill out the info form, and book a call.

If you are buying a 2021-23 system, please visit that product page and hit the "reserve now" button.

No. Not playing favorites for whoever has the biggest checkbook.

• VS30 Sprinters (2019 or later chassis) with nothing under the passenger seat base
• Will NOT fit chassis-cab sprinters with a low seat base as they have an extra brace under the passenger seat base. It MAY fit a chassis-cab with a high seat base (non swivel).
• Aftermarket swivels WILL NOT work at the moment without some modifications/spacers. We are working on native fitment with various swivels

• Winnebago Revel: fits 2021 and later without any modifications
• Storyteller Overland: fits all Stealth/Classic. Beast mode requires a bit of extra work to move a fuse/relay panel
• Thor Tranquility: Fits but requires extra work to relocate Thor installed components
• Anything else: please email a picture of what's in your passenger seat base with the plastic cover on the side taken off.

At the moment, we are not supporting DIY installations. We may support DIY installations in the future. If you are interested, please email us and let us know.

• Check out our installer map for dealers/installers. Please note that all of our power system installers can also install stereos!
