Re: AS above: BUYER BEWARE!!!!!!!!
We are only passing on our experience. Your question was fine. Sorry if I sounded sanctmonios with my question to you. If you have say a 14,000 lb 5th wheel empty and load 4,000 lbs in it you have got one heavy critter. 900 lbs is definitely not enough. 3,000 lbs seems about right. The 5th wheel comes furnished. 3,000 lbs of clothes, dishes, groceries, tools etc is quite a bit.
Most of us don't fill our water tanks past 1/2 full and empty our holding tanks prior to moving so we save that weight. I would also go with optional heavier axels, wheels and higher load range tires if they have them. Every little bit helps. If you stay with the better fulltime RV manufacturers they usually don't have many problems packing the weight. Those manufactures tend to put the heavy duty chassis under their RVs.
Just remember what you get moving down the road, you also have to be able to stop it. I tend to believe you should use the mid sized trucks to tow the BIG 5th wheels. I've seen too many little itty bitty short beds towing huge 5th wheels. Not safe. Just my opinion. :laugh:
