Well suggestions will lead to opinions! Are you new to campers in general? I have owned 3 and after the first 2 I formed one of those opinions! Mine is I hate EPDM rubber roofs. Most of the time they are fine but I often camp in wooded areas. All it takes is one branch to rub across the roof to cause issues. Something to keep in mind.
As far as toy haulers go they are no more difficult than regular campers to maintain the only difference is they have a big back door and room to put a toy or 2 inside.
Anyway you ask about brand preference, for my third one I went with a more industrial type and less focus on the frills. I chose a Forrest River - Work and Play. Mostly because it has a solid one piece aluminum roof (no more rubber roofs for me) short of converting an Air Stream this was a logical choice. I also like the heavy duty design of the Work and Play. Heavy Duty usually means Heavy weight but actually this 27 ft 5th wheel weighs about 200 lbs less than my last 31 ft bumper pull trailer.
Anyway - I recommend that if you are just getting started that you find a used toy hauler in good shape. First off you need to find out if you really are cut out for trailer life. Second off let the first buyer take the higher depreciation hit.
If you are already experienced with campers then you pretty much know what you are in for.
Good luck: here's a pic of my latest.
