I don't know if a dealer would do such an inspection, but you could probably find one of those mobile RV/mobile home repair people to come out to look it over for you.
With these older ones, they're really worth what someone is willing to pay for it. In light of that, 1996 was the last year of the 1550 and it had suffered from slow sales in the last few years, so these later, small models are harder to come by.
Granted it won't be nearly as good as a physical inspection, but if you can get a bunch of good, high quality pictures of it (20 or so), post them up here and we can give it a once-over from those and maybe alert you of things to look for or have someone else (I hate to use the word professional) look at.
