In these scenarios, I suppose you will eventually figure out what to bring along with you to cover the bases the best you can... Obviously all sites will be alittle bit different...
I saw a RV one time that had a power lift platform for a wheel chair...
I am always sitting at our local WALMART Parking lot driving MS DAISEY for grocery shopping and I see alot of handicapped folks coming and going. Most of them are carrying a folded-up wheel chair and they get it out of the back of their van's and car's and get it setup then the handicapped person gets out of the car and gets in it...
