I am new to the forum and have been reading old posts for what seems like days now. I thought I had my mind made up on a hawk,(was also considering a panther) with the basic components, heater and fridge. Now, it seems like I am reading all kinds of complaints about both the heater and the fridge. Is the heater that loud? I will be winter camping (from Idaho), and have read about the olympian heater. I also like the idea of no battery use with this option. Will FWC or ATC install these? Will they plumb the lines so you could hang it yourself? The other question I have, and this shows what I don't know, is the fridge. If you were to get an Engel,this would obviously have to run the whole time off of the battery. Can the battery in the camper charge from your truck when it is running? Will the solar panel keep up with the Engel if you were to go that route? I appreciate all of the help. Thanks.
