2027 Heartland Sundance 28DB Buying Guide

Is the 2027 Sundance 28DB the Right Family Fifth Wheel for You?

The 2027 Heartland Sundance 28DB is a family-oriented fifth wheel built around a rear double-over-double bunkhouse, a central living and kitchen area, a full bathroom, and a private front queen bedroom.

At 34 feet, 7 inches long, the 28DB offers sleeping accommodations for up to ten people while remaining shorter than many large bunkhouse fifth wheels. Its floorplan combines permanent bunks, a U-shaped dinette, a tri-fold sofa, a private bedroom, large holding tanks, a tankless water heater, solar equipment, and extended-season construction.

The Sundance 28DB may be a strong choice for:

· Families traveling with children or grandchildren

· Buyers moving up from a bunkhouse travel trailer

· Couples who frequently host overnight guests

· Seasonal campers

· Families who want permanent beds instead of converting furniture nightly

· Buyers who want a fifth wheel under 35 feet

· RVers who need generous gray-water capacity

· Owners who want solar and second-air-conditioner upgrade options

· Buyers with a properly equipped tow vehicle

The 28DB has a published gross vehicle weight rating of 9,995 pounds, a dry weight of 8,515 pounds, and a dry hitch weight of 1,585 pounds. Although those figures are lower than many large fifth wheels, tow-vehicle selection must still be based on payload, rear-axle capacity, hitch rating, tire capacity, and expected loaded pin weight—not advertised towing capacity alone.

What Does “28DB” Mean?

The letters DB refer to the double-bunk arrangement at the rear of the coach.

The published floorplan shows:

· Rear double-over-double bunks

· Bunk storage

· Rear wardrobe

· U-shaped dinette

· Tri-fold sofa

· Optional theater sofa

· Optional freestanding table with two chairs and a bench

· 11-cubic-foot refrigerator

· Central kitchen

· Full bathroom

· Linen storage

· Private front queen bedroom

· Bedroom wardrobe and dresser

· 19-foot awning

This layout is designed to give children or guests permanent sleeping space while preserving the main living area for normal daytime use.

Rear Double-Over-Double Bunkhouse

Permanent Family Sleeping Space

The defining feature of the Sundance 28DB is its rear double-over-double bunk arrangement.

Permanent bunks can be more convenient than converting a dinette or sofa every evening. Children can leave bedding in place, and parents can use the living area after younger campers go to sleep.

The bunk area may work well for:

· Two to four children

· Teenagers

· Grandchildren

· Occasional adult guests

· Extra storage during couples-only trips

Before purchasing, confirm the dimensions and published weight rating of each bunk on the exact RV.

Bunk Storage and Wardrobe

The published floorplan shows storage beneath the bunks and a wardrobe beside the bunk area. This gives children or guests a dedicated place for clothing, shoes, bedding, toys, and personal belongings.

During your walkthrough, inspect:

· Bunk mattress thickness

· Guardrail height

· Ladder or step access

· Reading lights

· USB-C charging access

· Ventilation

· Window placement

· Emergency-exit access

· Wardrobe depth

· Bunk-storage access

· Privacy from the main living area

Who Can Comfortably Use the Bunks?

A double bunk may technically accommodate more than one child, but comfort depends on age, size, mattress dimensions, and weight limits.

Ask:

1. What is the weight rating of each bunk?

2. Can an adult sit upright comfortably?

3. Is there enough room for two children on one bunk?

4. How is the upper bunk accessed?

5. Can bedding remain in place during travel?

6. Are charging outlets available?

7. Is there a dedicated emergency-exit window?

Sleeping Capacity for Up to Ten

Heartland publishes sleeping capacity for up to ten people. That total is based on the combined use of the rear bunks, front queen bed, U-shaped dinette, and tri-fold sofa or applicable furniture configuration.

A coach that can technically sleep ten may still be most comfortable with fewer occupants during longer trips.

When evaluating the layout, consider:

· How many people can sit comfortably during the day

· How many must convert furniture every night

· Where bedding will be stored

· Bathroom demand

· Refrigerator capacity

· Fresh-water consumption

· Gray- and black-tank use

· Clothing and personal-storage needs

· Available cargo capacity

The key question is not only, “How many people can it sleep?” It is also, “How comfortably can our actual family use it for several days?”

U-Shaped Dinette

The standard floorplan shows a large U-shaped dinette measuring approximately 38 by 82 inches.

A U-shaped dinette can serve several purposes:

· Family meals

· Games and activities

· Schoolwork

· Remote work

· Trip planning

· Additional sleeping space

· Indoor seating during poor weather

For families, the dinette may be one of the most frequently used areas in the RV.

What to Check at the Dinette

· Can everyone sit without crowding?

· Is the table easy to raise and lower?

· Is storage available under the seats?

· How comfortable is the converted bed?

· Can the table support a laptop or schoolwork?

· Is there enough aisle space when people are seated?

· Can the refrigerator be opened while the dinette is occupied?

Standard Tri-Fold Sofa and Optional Theater Seating

The floorplan shows a 60-inch tri-fold sofa across from the entertainment area. Heartland also lists theater seating as an available furniture option.

Tri-Fold Sofa

The tri-fold hide-a-bed sofa uses a residential memory-foam sleeping surface on applicable configurations. It may be preferable for buyers who need maximum sleeping capacity.

Advantages include:

· Additional guest bed

· Daytime seating

· More flexibility for larger families

· No inflatable mattress required
