Pat,
You have received outstanding advice. Look at all four scenarios carefully: low coolant, bad hose from the AquaHot tank to the surge tank, bad mixing valve and cold water issue coming into coach. Below I posted a picture of the piping that Rudy told you to check with the mixing valve. The mixing valve has the black knob where the hot water goes in and warm water goes out. This piping is located below the black diesel burner.
Also these units need annual service. Has the unit had its annual service and the mixing valve exercised? Exercising the valve is simply moving the valve knob to the left & right and then recentering--usually only can be done with the diesel burner removed. Instructions on servicing your unit are posted in the "Documentation" section of this web site under "heating systems". You can evaluate whether you have the tools & ability to perform the service. If you have any questions, email me & I'll send you my phone number.
