Choosing a Tankless RV Water Heater

I am trying to compare tankless RV hot water heaters. The two I found are the Girard and Precision Temp. The Girard has less BTUs and states that to increase heat you need to decrease volume, which sucks for taking a shower. Is the Precision Temp unit the same? I am a full-timer and travel to and stay at winter locations. Phil W. (Rapid City, SD)

Phil, I’ve seen the Girard unit at the National RVIA Trade Show, but I’ve never installed one or had it tested. I haven't seen any reviews about it either. It’s relatively new on the market. The Precision Temp RV 500, on the other hand, has been around for a few years and I’ve personally installed and tested one. Though I didn't take a shower, (it was a customer's rig, after all!), it worked perfectly during testing after the installation. Click here to read my full review of the RV 500.
