waterwolf;
I know that you are sincere in your question and I know why you are asking. In order to help those that may have an answer for you, give them some more information. Propane tanks full or empty, holding tanks full, 1/2 full or empty, what options do you want included, etc. This will make a lot of difference. My guess is that the published weight of 8443 is close to the empty weight, no options of the model you are looking at. I'm sure others will weigh in with more numbers.
