with a small trailer you will not be able to sleep 6 people. The kids would need to sleep in a tent or lean to. As to dump station, all parks have a place to dump. The only place that does not have dump facilities is federal land where people are boon docking. I use a F- 150, 8 cylinder, to pull my 24ft TT. It has been no problem. I would suggest that you look at manufactures web sites to see what models they have. I have a walk around queen bed. They call it an island bed. That was a must so we would not have to crawl over one another at nigh to visit the bathroom. Mine is a 2016 White Water Retro by Riverside. It looks like a trailer from 1959, but has all the conveniences of the modern TT. You can look Riverside Manufacturing web site and then visit others, such as Forest River. Take your time and pick the one that is best fit for what you want. There are wet baths, commode and shower together and some are separate shower and commode, as ours is. There are bunk beds in some Forest River TT's and most all TT's have a table that lets down into a bed. If you ask what is best you will get dozens of different opinions. Take a look at the various manufactures and then pick the one you like. Welcome and have a wonderful, fun, and safe time camping.
