Hi Lydia, thanks for reaching out! The PD4135KW2B is no longer in production, so we aren't able to offer that exact model anymore.
A great replacement is the Progressive Dynamics 4000 Series Mini RV Converter with Charge Wizard and AC/DC Distribution Panel, part # PD4045KA. It works with lithium, flooded lead acid, AGM, and gel batteries, includes a built in Charge Wizard for proper battery charging, and gives you a couple of extra DC fuse positions and two additional AC branch circuits compared to the older unit. It's a nice upgrade if you're replacing an aging power center. The current price is listed on the product page and may change over time, so that's the best place to see the most up to date pricing.
Just out of curiosity, what RV do you have, and are you mostly camping with hookups or spending time off the grid?

I bought the PD 4045 because I wanted to upgrade my battery to lithium, but my stock converter didn't support the lithium charging profile. The replacement looked a little scary with wires everywhere, but it went smoothly. About 3 hours total. The converter works well and it operates much quieter than the original converter. Totally pleased. E-trailer's service was as usual -- quick delivery no problems. -Mike T.
