Congrats on the truck Jay!!!! My camper originally only had one A/C and was a 30 amp. I upgraded to the second A/C before i purchased. My unit has a sunlight in the bunkhouse over the 5th wheel, thats the hole they use to install the second A/C, so no cutting was involved. It actually comes from the factory as an option.... second A/C was a $700 upgrade and i said do it. Whenever i go to a 30 amp spot, the only thing i cannot run is the second A/C. I have the 15.5 as my main unit for sure, and i believe my front A/C is 13.5. Jay and i know ive said it a few times now, but go withy the 2500lb. bags. I love the dodge trucks, they already come pretty stiff in the back, ( compared to Ford, Chevy not so bad) so u wont need the 5000lb. bags, youll just be wasteing the few extra bucks. As a matter of fact, u really dont need them at all, but i also like having the extra insurance and prolly would install them too. As for what i paid for my unit, i have no problem sharing at all, but it was over a year ago, so im taking a shot at it. I want to say around $35k, ill ask the wife, she remembers better than me. I just make the money! haha!
