Umm, seriously? ..ok. So what dually truck do you want to compare to a 2500 with all the mods you can throw at it at what cost for modifications?? There is NO 2500 that will be as built as a 450 or a 550....even a 350 has more punch...they are not the same...my Cummins is a HO...it has a bigger brake package, bigger springs,overloads and sway bar, a wider stance and much more stability that no 2500 can compete with..My point was to say the investment is worth turning your attention and piece of mind of choosing any RV of your choice...and not to worry as you go bigger... A 250 rig won't give you all the options without having to buy another truck if you expand to something larger. What if your wanting to have a 5000 pound TC and pull a trailer with toys or boat or even go with a 5th wheel that's 20 thousand pounds? Dually is you answer...in my opinion.
