Help with RV build terminology

[bodzcampers]

Comparing a few Park or Destination Models and some terminology I don't understand which makes it hard to compare models.
1. What is a Cambered Chassis?
2. Tongue and groove vs. 1 piece floor decking? Implication?
3. 5" vs. 4.5" Truss Roof Rafters...What are truss roof rafters?
4. Bowed or crowned or radius truss roof rafters? On top of it.
5. Extruded I beam frame.
6. How far apart should floor and wall joists/studs be ideally?
7. Rack and Pinion slide vs. hydraulic slide

well that's a start as i sift through brochures.

Thank you for clarification.

#1-not for sure but guess that axles are cambered so that wheels will be perfectly vertical under load.
#2 one piece is just that. The tongue and groove is where sheets of plywood mesh like sticking 2 forks teeth inside each other.
#3 how tall the truss is- its what supports your ceiling and roof
#4 dont know, seem like synonyms to me
#5 I dont know if your talking the chassis frame or wall/ floor or roof structure, so I wont guess.
#6 homes are on 16" ideally, rvs I couldnt say for sure.
#7 rack and. Pinion is a motor that has a gear that turns on teeth that are on a track basically, hydraulics have a pump and rams with lines Inbetween with fluid in them.

Thank you. I appreciate your help in narrowing down these concepts.

You are quite welcome! Sorry I couldnt answer more.

#4. Bowed, crowned or radius truss roof rafters means the roof is curved as opposed to being flat so water will flow off to the sides easier and not pool up.
