They do look similar, especially with all the external decals off. For sure Its a pleasure way though. I know because its mine . I have all the pleasure way paperwork with it too.I think that's a GTRV Westy, not a Traverse.
I know the Ad says Pleasure Way, but some of the construction details just scream GTRV to me. (As someone who has dissected a GTRV and transplanted many of the bits to another van.) Both companies did pop-top Ford vans, both companies have good reps, so I wouldn't sweat it if I were in the market. If anything, the owner may just not know what they have.
Or, potential scammer using stolen pics. Looks like a good deal for someone, if it's real, though.
