Re: HELP, Towing 40'5th wheel with Ram 2500 4 x 4
Don't know about Dodge, but in my GMC, the 'Tow/Haul' button reprograms the transmission and should always be used whenever towing or hauling more than some percentage of the allowable weight. Used to know what the percentage was, but haven't towed/hauled anything recently so I have forgotten.
You need to subtract the weight of the washer/dryer from your CCC, so I guess you are now under 1800 pounds for your stuff. A trip to a scale will tell you exactly how you are doing. It will also tell you where you stand via your truck. I'm thinking you might be a bit over its limit. You might want to consider a 3500, or possibly a heavy duty 2500. Check the weight limits of your truck, and these other options.
The weight limits of the truck and the trailer are of most concern when you are moving. If you carry the dog in the truck (and you should), then his weight will only apply to the weight limit of the truck, and not the trailer.
