A quick follow up on this, since I know there are a LOT of vans out there that have this model inverter/charger.
I ordered the newer model of this unit http://www.amazon.com/Tripp-Lite-Pow...ords=rv2012+ul
and figured I would just see if it would possibly fit even though the dimensions listed were pretty far off from the unit that was in the van.
Well, what I found out was that the unit DOES fit, but you have to grind off a few of the mounting "feet" that stick out on the sides. Which is exactly what SMB did to the original unit as it turns out.
I am awaiting a few parts (lugs and power cables) because I did have to change just one wire due to the different connection type on the front of the unit.
Appears to fit and work fine.
This is mind-numbing close -in, hurt your hands and contort your body type work since the fit is so tight, but it will work for those considering a replacement of their non-functional tripp-lite inverter/charger.
