With all do respect, I think you might be biting off more than you chew. A 25ft TT does have its limitation. Camping has its difficulties for those who have not anticipated the stress, such as walking to central facilities in the weather, using steps without handrails, and the closeness of the toilet facilities in the rig...to name just a few. I understand accommodating good friends make one want to try even the most difficult situation. Perhaps a joint weekend at a hotel at a destination resort, like a casino, might be a good trial run. Out where we live there are also many lovely RV parks with adjoining hotel/motel facilities. Perhaps a campground and a motel room would be a good first try. Best of luck to you, I applaud your good intentions.
