http://www.myrv.us/Pgs/RV/50amp.htm, did the search for you kozzy45 this is link you need to help you and install a 50 amp service outside at your rig, just add a 50 amp 2 pole breaker in house panel if it can handle the load most can depends on power box. I did it this summer, my issue was had long run 150 feet had to run #2 Mobile home service wire from House 50 amp breaker to the 50 amp service outside box I got from Home Depot. I could have use 6gauge put was cheaper to run the mobile home wire which does not need conduit and can be direct buried under ground. Lot cheaper that way but sure is mess to deal with stiff is not the word in working with #2 aluminum wire. this topic was under General discussion back in August under 50 amp service.
