Found it! But CCC looks awful low?

we own a 2012 X17Z. We have owned it since new and in the first year had trouble with the axle and tires. I do not typically stress too much about overloading the camper. we load what we need mostly cooking gear, food and clothes. Bikes, generator, and any outdoor items like fuel, stove, lantern, cooler full of drinks etc... go in the back of the truck. We ended up replacing the axle and I elected to purchase 14" wheels and tires after the first long trip. The axle is still what Jayco installs on them. They covered the part but not the installation so I installed it myself. The additional ground clearance and added carrying cushion from the larger tires seems to be doing well. I tow the trailer generally around the speed limit. We have made several 3000 mile trips with it set-up this way. Sometimes we are carrying water and sometimes not. never really seem to notice a difference. I often wish we had a larger trailer now that we have a larger truck but when we purchased this trailer I owned a smaller TV and was not comfortable towing anything bigger. I guess overall since it has been sometime since the axle and tire change out we are happy with the camper. One thing to consider that I had not thought of before is looking at water tank capacities. The grey water tank is a little small. after a few showers it is full. And it really is nice having a shower in the camper!
Good Luck!
