fifth wheel to truck camper comparison

We have a 2006 Chevy 3500 4x4 diesel. We pull a Sunnybrook 32' with 3 slides for winter trips to Florida that weights in close to 15,000 lbs. We also have a 1997 Bigfoot 9.5' Pickup Camper for shorter trips after we're home from Florida. This is the second pickup camper we've owned through the years. As we have a 3500 that we ordered with the camper options and it's a 4x4, the truck bed is slightly higher which makes for a little more of a top heavy load, but the 3500 seems to do a good job of hauling it. Our mileage towing the 5er is 11.5 to 13.5 mpg and traveling with the camper is 17.5 mpg approx. There is a little more sway turning corners with the camper than without it, but the overall ride is basically the same as with the 5er. We have talked about and considered putting overload springs on, to help with the cornering, but don't feel it's an absolute necessity. According to the sticker on the camper, its weight is 1500 lbs (which might not be exactly accurate) and with it loaded with supplies, food, water, propane, it's probably closer to 2,000 lbs. As far as the truck noticing it less back there, I think the tongue weight on our 5er along with other items we haul back there is probably real close to the weight of the camper and doesn't seem to make much difference. We like the easy and quick traveling with the camper vs. all the prior prep to moving the 5er when making several overnight stops and sight seeing in a 1 to 3 week excursion. Also, if you can park your truck camper vehicle in a space, you can park it, whereas the 5er requires different tactics for parking space and many stops can't be made due to no parking to hold the length of the truck/5er combo. Every camping option has it's pros and cons.
