Looking for a 5th Wheel

I am in the preliminary stages so the first couple of questions are

1) What brands are notorious for troubles?
2) What are the pros and cons of the rigs you have?

I like the Coachman Chaparral models. They have a lot of headroom, even in the master bedroom. I am also not looking for models that have multiple bedrooms or bunks.

1. there are no brands that are notorious for trouble. Just choose the floorplan you like in a price range you can afford.

2. my trailer is a old 11200 lb '97 28 RK with two slides. My '03 2500 Dodge/Cummins has pulled it with ease for 15 years now.

A F250 Ford diesel or gas has a 6100-6340 rawr that will carry all the weight in the bed.
Gas or diesel trucks rear axle may weigh the same .....within 75-100 lbs or so.
The newer gen F250 trucks rear axle can weigh in the 3000 lb range from the factory leaving approx 3100-3300 lb for a in the bed payload. I figure my pin weights using those numbers when looking for a trailer including type of trailer.
Now....if you choose a F250 with the heavy service/camper package it has the same front and rear suspension as the F350 srw truck.

The F250/F350srw has about the same tow rating for all types of GN/5th wheel trailers...not just a rv trailer.
