NOTE WELL the return policy!! The builder's opinion is that the unit is too heavy for the roof of my particular van. That is not Velit's fault. What I did not expect was the only return within 30 days if it does not work return policy. I did not even think to check the policy because...well, who doesn't have a 30 day return policy for an unopened box? I take responsibility for not checking, but I find this policy completely unreasonable. Now I have a $1700 (including shipping) unit that I cannot use.

Good product and solid customer… Good product and solid customer support. Our 2000R unit worked great on four 100ah lithium batteries. Install was a bit tricky, but got good answers from the support guy. Looking forward to the housing extension for thicker roof installations.

Good quality kit with and reliable startup Product came on time, Velit had good communication. Everything was exactly as expected.

Diesel Heater Upgrade I just replaced my diesel heater with the Velit Gasoline Heater, it is definitely an upgrade. I no longer have to carry diesel and the fuel pump tick is not noticeable. I also tested the temperature control that shuts off the heater at 3 degrees past the set point and starts again at 3 degrees below the set point. I would recommend this heater for any RV that runs on gasoline.

The unit has no air filter The AC unit cools and operates well. The unit does not have an air filter. Running any AC unit without an air filter will eventually clog the evaporator coil with lint which will destroy the efficiency of the unit. The evaporator coil is wet from condensed air causing the lint to stick to the coil, reducing airflow and severely impacting the cooling. It is very hard and messy to clean an AC evaporator coil. The support technician advised me they are aware of this and working on a fix. Once filter issue is resolved the unit is worthy of the highest rating.
