Re: TrippLite Powerverteres
It would be good to post the model number of the tripplite you are looking at.
I have the standard tripplite RV1512UL that came with sportsmobiles in 2004. I have had no real issues with the unit. I have only had one contact for support and that was for the panel for the remote option ( the panel was not used in the sportsmobile installation) I was sent one for free.
Two things to look for are the inverter specs, you want to make sure that it will meet your expected load, which looks like a microwave will be the big item.
The second thing to look at are the charger specs, this could be the most important part as it could impact the life of your battery investment. If you post the model I will be happy to review the spec and try to point out the pros's and con's.
