thanks Donna, we really appreciate the additional comments and agree!

He Ellen, what a huge topic! Im not versed on the exact insulation used by Entegra but we’ve been very happy with our coach, especially in cold climates. We’ve spent time with friends (RVLOVE) and they had a 2014 Tiffen Allegro Bus gas and the insulation didn’t compare. There were multiple reasons for this but i think the primary was that our storage compartment (we call it our basement) was an enclosed space that was fully heated by our Aqua-Hot system. This meant that below our living space was heat and therefor our floors were usually much warmer. This combined with double pane glass and well insulated walls meant that our heat tended to run about half as often as our friends in a gas coach and our heat was much more even (a lot less cold spots, or hot spots for that matter depending on climate). Now that said, we also have an Aqua-hot system, so our heat not only radiates from the warm basement but also we have registers all around the coach to provide heat (I don’t think i’ve ever seen this type of system in a gas coach but i’m sure it exists). That said, its a big price jump to diesel as you said so you need to weigh the pros/cons for yourself.

As for maintenance, yes diesel costs more to service as everything is bigger and takes more fluid. As an example our engine holds about 7-8 gallons of anti-freeze and probably about the same in motor oil (a little less but its over 6 gallons). That translates to higher costs and there are also a lot of filters including fuel filters, hydraulic filters, air/water separators if you have air brakes, air filters (our air filter cost 150 bucks compared to probably 30 for a gas coach). Now all of that said, we get 20,000 miles to an oil change so even though it costs more, we can go further. We also get a much higher carry capacity which comes in handy if you are full time. I also find that diesel seems to be less affected by weight when it comes to gas mileage, we average about 8 mpg in our rig. Lastly we have a 100 gallon fuel tank and many of the new diesels are 150, that means fewer stops. For a cost estimate if you went HUGE like us at 45″ i would say a safe estimate for annual maintenance cost is 1000-1500 per year all in. You can definitely get that number down if you have a trusted mechanic but its good for budgeting. Gas will vary greatly on the mileage you put on the coach and how often you need to do oil changes. Hopefully that answered some of your questions and of course let us know if you have any other questions!
