Well I'ver read every post on this always counterversial subject. I must say I have really enjoyed the many technical posts on formulas and such. Each side basing their strong opinions on fact and science vs. plain old IMHO type stuff. Bravo to the engineers out there! However, the thread really got wayyy to technical from the OP's basic question. Sure he asked about towing power and such, hence the turning point of the thread. But, you would think there would be more imput from the every day joes out here in RV land such as myself, of the "other" reasons, besides floor plan, in chosing one type of rig over another. So, this is where I come in with "MHO"! I do not full time. I am for the most part a week end warrior with one or two long trips a camping season, somewhere between April to November in the north east. Or about 40 nights a year (how sad). For "ME" I could not justify a tremendously more expensive diesel rig over my 2011 Georgetown V10. Sure I could of bought an older diesel, trading age of my rig to get a darn nice used DP, but I still could not justify the higher operating costs and fuel to my yearly cost to own, operate and use with such limited use. Like most, I do dream of moving up to a DP, whether its heading to retirement, or circumstances change with DW and I and we can get more use and enjoyment out of the lifestyle. If the money equation (aka what can I/you afford?) was not one of the prime deciding factors, I would think 80% or more of class A's on the road would be DP's. However, most of us have to deal with the reality that $$$$$ doesn't grow on trees.
I am extremely happy with my V10 as it does everthing and more, at a modest investment, that DW and I ask or need from it.
