You are 69.6% of rated front axle weight the bare minimum IMHO is 75% and anything up to 95% would help. To get 75% you need to get 270 more pounds on the front. I would try to move 520 pounds and that would get you to 80%. How do you do that? Keep in mind that any weight behind the rear axle takes weight off of the front axle.
Is your water tank in front of the rear axle or behind the axle? If in front make sure it is full if it is behind carry the bare minimum you need while driving and fill at destinations. If your black and grey tanks are behind the rear axle keep them dumped. Move anything in cabinets and storage areas that is behind the rear axle as far as you can forward. Heavy stuff up front and bulky stuff to the back under the dinette seats are great for this. Does anyone ride behind the rear axle? Your cab over area can hold 150 pounds no problem. Yes it is hassle to remove the chairs for example from your overhead at night but it might be necessary. I do not recommend telling wife she needs to gain weight. After you have done this reweigh and if you are over 75% then hook the Jeep back up and see how it does.
