AC Upgrade Help!

I recently purchased a 37' 5th wheel with 4 slide outs. It currently has 1 AC but is pre-wired for a second. I want to replace the existing and add a second unit. I live in Texas and need all the cooling I can manage. I have heard great things about the Coleman Mach 15's, what are your thoughts?

Please help with the following:

What size units?
Make and model suggestions?
Heat pump, heat strip or neither?
Should I try to stay under 30amps total?


Thank you in advance!

    Not a lot of difference in 13.5k and 15k honestly. Are you adding a non-ducted AC with controls on the unit? Or a ducted unit? Or a unit that is controlled by the central thermostat?

    If you're using the thermostat, that may focus what units are compatible.

    Be aware that you need to order ducted/non-ducted and the right control setup.
