Does a travel trailer detail take less time than a Class A of the same length?

Usually yes -- travel trailers are more often aluminum-skin or simpler gelcoat surfaces that wash and dry faster per foot than a painted motorhome body with more graphics and roof equipment.

What adds the most time to a Class A detail?

Painted body surfaces needing careful hand work, more roof-mounted equipment to work around, and multiple slide-outs each needing individual seal and panel attention.

Should time estimates be based on length or RV type?

Both, but type matters more than most detailers initially assume -- a length-only formula under-times motorhomes and over-times simpler trailers of the same length.
