You talk about the really big tent you can take now, with the oriental rug and big stuffed pillows so she can recline in comfort while you feed her grapes from the big cooler you can now take. You tell her about the fresh food you can take in that cooler instead of the MRE's and dehydrated stuff. You tell her about the inflatable shower you can take so she can have a hot shower every day with all the water you can now take. Tell her about the telescope you can take now so you can search the heavens looking for an unknown comet to name after HER, so that her name will live on for eternity as your love for her will transcend all time. Tell her about the hammock you have room for now so that she may relax and sway to the rhythm of the wind.
Women really go for that relaxing in comfort idea.
Mention you can take the bicycles AND the canoe now. Let her think of some stuff you can take now. Women love to think. You plant an idea and let their imaginations do the rest. Women have really good imaginations.
