personally if I was to BUY a inline, I would look at what I need and want, and then find a company and have them MAKE me what I want
I live close by two company's now
Haulmark and Worthington
and I know countless people that had them build a trailer to there spec's and been very happy with results
BUT like everything today, you cannot JUST say"X" brand name and your good, every company lets lemons go out the doors
one big key to buying a trailer IMO< is be honest with what your needs and future plans are
, get what you want the at time of buying
look at it as an investment, buy once cry once!
as many things are not as easy to add later on, and regretting not getting THIS or THAT upfront, can cost a lot more to get the second time
if I was to make a list of things I wanted
, size would be first(what ever you want here)
I would want finished ceilings and walls, in floor E track in the floor and on walls from the get go!
spare tire holder, a set of shelves/cabinets!
decent lighting!indoors and on ramps!
GOOD vents on walls(possibly ceiling too, all the more so if you plan to store anything in it)
pending size, 16 on center framing, floor and walls and ceiling!
a 120 volt power supply, back up lights, and HECK, wireless rear view camera system!
and what ever flooring you desire, coated, covered or??
those would be top of my list of options!
