Two suggestions for making life easier.
1) Get a pair of walkie-talkies to use while your spotter is helping you position the TT (at campsites, home, gas stations, etc). So much better than arm waving and yelling.
2) Boxes of disposable gloves. We do a lot of dry camping and cutting down on needing to wash our hands is a big plus. We take them into CG bathrooms, use them when dumping tanks, use them for food prep, etc.
Beyond that, it's all personal preference. We keep a second set of linens in the TT and change the sheets and towels on the last morning. Then we clean the TT and prep it for our next trip as soon as we get home. That way we're focused on packing mostly food and clothing when a couple of days away from each trip.
We also have small bins for sundries and pantry items to quickly move them to/from the TT when at home. Our summer heat prevents us from keeping everything inside between trips. We go out twice a month in season and this works for us.
