rick webb - If I do have any questions I will reachout. As while I am faily handy(replaced doors, installed outdoor lights, installed my current tow hitch). I am not familer with the trailer world, but it does sound very much like dril new holes and bolt new springs, holders, and axle to frame which are in my wheel house.
As for trips, I am fairly central in Oklahoma(but no realy good lakes here or nearby). Thus a lot of places that I would want to spend a week or two are 1000+ miles from my location. The trip I just did was to Rainy Lake in MN(1100miles). I would love to go again for 2 weeks. Other places I want to go in the next couple of years are the Fl Keys(1500 miles), Chesapeake Bay(1300miles), lake Powell(1000miles), and the great lakes(800 to 1500 miles). I would love to go the Puget sound, but at 2000+ miles it's not very likely unless I did 3 weeks(still posiable, but would be a 1 trip year). Also my job has a lot of 3 day weekends(9/80 work schedule) and a few 4 day weekends each year, so I would like to do shorter trips about once month in the sailing session. As I very much see this boat as way to get out and see the country and to vet the idea of aming for relocating some where I can have a 30ft boat on a big bay or open water. Side note why do people put 30ft to 40ft boats in small lakes(also how do they get the boat there). That's why I am now looking at trucks as why I can tow with my current suv. Reading here and other places, a truck would make it much easier and less stress full.
Big advantage of the slides is they attach with u bolts No Drilling easy to adjust if you don't get them quite right at first. If you put your own hitch on you can do this.
